Remove
  using namespace std;
from Riostream.h, which has huge consequences for all of ROOT.
Riostream.h is now a simple wrapper for fstream, iostream, iomanip for backward compatibility; Riosfwd.h simply wraps iosfwd.

Because of templates and their inline functions, Riostream.h needed to be included in headers, too (e.g. TParameter.h), which violated the assumption that Riostream.h is not exposing its using namespace std to headers.
ROOT now requires R__ANSISTREAM, R__SSTREAM, which does not change the set of supported compilers.

Without "using namespace std", several identifiers are now prefixed by std::; e.g. roofit/* source files now have a using namespace std to keep their coding style.
TFile::MakeProject() now generates "using namespace std" to convert the CINT-style class names into C++ ones.

   o PiecewiseInterpolation, RooAbsCachedReal, RooAbsCachedPdf

     - Follow adjustment in RooCacheManager


   o RooConvCoefVar, RooEffProd, RooResolutionModel, RooErrorVar, RooProjectedPdf, RooAbsHiddenReal

     - Migrate to getValV


   o RooProdPdf

     - Follow adjustment in RooCacheManager     
     - Migrate to getValV


   o RooVectorDataStore

     - Various small fixes

     - Allow storage of non-constant 'track-and-change' cache entries.
       These are cached PDF nodes that are not constant, but need
       to be recalculated when selected parameters change. A 
       RooChangeTracker data member is added to the vectors to
       do this dependency checking, and recalculation (as needed)
       is performed in method recalculateCache() to be called from
       the test stat before looping of the data.
       

   o RooAbsReal

     - Introduce new non-virtual inline getVal() methods that handles
       clean-cache state cases and delegates all other cases to a 
       virtual method getValV() that corresponds to the original
       getVal() method


     - Add 'ignore' more to eval error logging protocal


   o RooAddPdf

     - Follow adjustment in RooCacheManager 
     - Optimize control structure in evaluate() to be more efficient
       (move conditional outside loop)

   o RooAbsTestStatistic

     - Add extra argument to constOptimizeTestStatistic to control
       activation of track-and-change optimization

   o RooRealMPFE

     - Migrate to getValV()

     - Add support for new track-and-change option argument in 
       transmission of const optimization request to servers
       

   o RooRealVar

     - Exploit new _fast flag of RooAbsReal to choose non-virtual
       handling of getVal()

     - Migrate to getValV() [ but still dummy ]

     - Small fix in attachToVStore()


   o RooNLLVar

      - Add data member tracking first use

      - After first use, trigger wiring of all caches in RooCacheManagers
        to speed up trivial cache selection decisions (i.e those where
        only a single cache entry exists)

      - Add call to RooAbsDataStore::recalculateCache() to implement
        track-and-change update prior to likelihood loop


   o RooConstVar

      - Migrate to getValV()


   o RooAbsArg

     - Eliminate flipACLean() protocol since no longer used

     - Simplify method opermode() now that flipAClean is abandoned.

     - In findConstantNodes() add support for change tracking
       and include nodes with "ChangeTracking" atttribute in
       list of constants. Mark all truly constant expressions
       with attribute "ConstantExpression"

     - Add extra argument to constOptimizeTestStatistic to control
       activation of track-and-change optimization  

     - In printCompactTree() also print valueDirty state when in Auto mode


     - Add method wireAllCaches() which propagates cache wiring request
       to all registered cache nodes on all branches nodes

     - Add transient data member with namereg pointer to string with
       current object name. Overload SetName() and SetName() and title
       to clear pointer whenever name changes.


   o RooAbsPdf

     - Migrate to getValV(). Eliminate handling of clean-cache cases
       as this is now done in RooAbsReal::getVal()

     - Disable use of RooAbsPdf::raiseEvalError() protocol as this
       is now communicated through RooAbsReal::logEvalError()


   o RooRealIntegral

     - Migrate to getValV()

     - Use setInhibitDirty() instead of flipAClean() in evaluate()
       when performing numeric integrations


   o RooTreeDataStore

     - In cachArgs() add code to select only cache items with
       label "ConstantExpression" as tree store is unable to
       cache track-and-change items

   o RooAbsCategory

     - When printing also show index associated to label


   o RooAbsOptTestStatistic

     - Add extra argument to constOptimizeTestStatistic to control
       activation of track-and-change optimization

     - In optimizeConstantTerms() when trackChanges option is active
       request change tracking for all component nodes of RooAddPdf
       and RooRealSumPdf, unless these components are RooProdPdf/RooProducts
       respectively in which case the components of these products are tracked
       
   o RooRealProxy

     - Use _fast attribute of RooAbsArg to directly return value cache
       of RooAbsReals if that is allowed


   o RooAbsCache

     - Add virtual method wireCache()


   o RooCacheManager

     - Add new method getObj() that takes isetRangeName as 'const char*'
       instead of 'const TNamed *' to be able to eliminate the conversion
       when in wired mode

     - Implement cache wiring - If at moment of the request only a single
       cached entry exists - always return that one from here one.


   o RooAbsDataStore

     - Implement virtual method calculateCache()

    o RooBanner

      - Increment version tag to 3.48


    o RooRealIntegral

      - Add (dummy) method callgrind_zero() and callgrind_dump() as hook functions
        to facilitate improved callgrind profiling

    o RooFormular

      - Eliminate overloaded getVal() as its functionality is now provided in 
        RooAbsReal::getVal()


    o RooAbsOptTestStatistic

      - Implement new fast-attach mechanisms for pdf and datasets: only readjust the
        buffer pointers of the dataset to the pdf observables, rather than reattaching
        the pdf to the dataset observables. This results in a _much_ faster 
        operation of setData() and no longer entangles the test statistics with observables
        of datasets that may be deleted during the lifetime of the test statistic

 
    o RooSimultaneous
 
       - Overload fillDataHist() with new version with correct normalization (from Scott Snyder)

   o RooAbsReal

     - Add interface to specify hint for plot sampling binning. This is useful
       for p.d.f.s shapes such as un-interpolated histogram p.d.f.s that may

   o RooAbsSelfCachedPdf

     - Declare embedded RooHistPdf as self-normalized to prevent
       superfluous calculation of unit normalization


   o RooDataHist

     - Add new named argument ctor that can collate multiple
       TH[123] into a N+1 dimensional RooDataHist which has
       an extra RooCategory to distinguish the source, as
       well as import single a TH[123] objects

     - Add ctor that can do the same, but specified from
       a map<string,TH1> specification.

     - Add new importTH1Set(),importTH1() utility methods to implement
       common functionaly of both new ctors

     - Add adjustBinning() method that encapsulates the functionality
       to adjust the RooDataHist observable binning to match that
       of a given (imported) TH1, which was formerly contained in the ctor

     - Speed up code in interpolateDim() by reducing number of required
       lookups of the observable binning definition.


  o RooParamBinning

    - Add tree printout of boundary functions, if defined in verbose
      printing mode


  o RooMsgService

    - Add special handling of PROGRESS message level: automatically 
      insert newline when switching from a PROGESS to another message level.


  o RooPlot

    - In verbose printing, add index number to printout of each contained 
      plotable object


  o RooGenContext

    - Fix for handling of observables with parameterized ranges

    - Eliminate forgotted debug print statement


  o RooAbsRealLValue

    - Implement new binning interface methods that take binning reference
      rather than binning name, for faster use in internal operations

    - Implement new RooAbsLValue methods with RooAbsBinning pointers


  o RooDataSet

    - Add new named argument constructor that can generically handle imports
      of TTrees, RooDataSet and can collate multiple RooDataSets into
      a N+1 dimensional RooDataSet with an extra RooCategory that labels
      the source dataset


  o RooDLLSignificanceModule

    - Tune some of the names of the produced output observables


  o RooChi2Var

    - Set the default error type to RooAbsData::SumW2


  o RooCustomizer

    - Modify the sterile build() routine to make the returned
      head node own all the created components rather than
      the customizer itself.


  o RooAbsCategoryLValue

    - In copyCache(), check that the value copied is in fact
      valid for the destination.


  o RooFitResult

    - Tune the line widths of the objects created in plotOn()
      when creating the error ellipse.

    - Add a method correlationHist() that returns a 2D histogram
      with the correlation matrix element values, which is labeled
      with the parameter names.


  o RooCurve

    - Add explicit handling for evaluation errors that can occur
      when sampling the function being represented. New constructor
      arguments control how evaluation errors are logged to
      RooMsgService, in similar style to RooMinuit, and control
      how the drawn output value is affected (as calculated, or
      substituted with a user controlled value).


  o RooFFTConvPdf

    - Add automated handling of FFT sampling windows of the 'physics'
      pdf and the 'resolution' pdf. In the new setup the second pdf
      is always assumed to be a 'resolution' pdf and its sampling window
      is chosen symmetrically around zero, regardless of the definition
      of the range of the convolution observable. The width of the sampling
      window, and the number of sampling bins is still tied to the "cache"
      binning defined in the convolution observable. Added setShift()
      modifiers allow the user to manually control the sampling window
      shifts on both pdf. The shift introduced by sampling a shifted 
      window of the resolution effect is correct a posteriori by
      performing a compensating rotation of the final FFT buffer.

    - Modify FFTCacheElem to cache a functional clone of both pdf
      with optional shift transformations applied through a RooLinearVar
      substitution of the original convolution observable. Instruct

   - Fix client-server reconnect handling for dataset observables
     with parameterized ranges in terms of other dataset observables

   - Add simplified createHistogram() method that takes
     string with comma separated observable names and
     three optional bin numbers. If bin counts are negative,
     the ranges of output histogram are automatically calculated.

     RooCmdArgs that can serve as backend for all user
     interface methods.

     objects to be cached in association with this object

   - Add recurseNonDerived option to branchNodeServerList

   - Overload printAddress() to so that RooAbsArg base address
     is printed rather than RooPrintable base address, which
     can be different due to multiple inheritance

     observables with parameterized ranges to cache.

   - Add interface methods to get and set the associated
     expensive object cache

     expensive object cache


 o RooExpensiveObjectCache

   - New repository class that holds expensive components of RooAbsArg
     function objects along with the parameters value for which the
     stored expensive object is valid. All newly created objects
     are associated with a default singleton instance in memory,
     but objects in RooWorkspaces are associated with a cache in the
     workspace.
    

 o RooMCStudy

   - Add Silence() named argument to ctor that will silence all
     RooFit messages during running below the PROGRESS level

   - Store generated number of events in fitParDataSet()

   - Add various named argument constructors needed by other code


 o RooCintUtils

   - New name space with CINT interaction utilities

   o RooAbsSelfCachedPdf

     - Follow changes in RooAbsCachedPdf 


   o RooCachedPdf

     - Add option to override default choice of cache observables
       (the normalization observables) with a specific set of variables
       to make it possible to also cache p.d.f values for all values
       of given parameters as well.

     - Forward analytical integration capabilities to actual cache p.d.f

     - Forward calls on preferred observable order to cached p.d.f


   o RooDataHist
       
     - Add option to bin dataset in alternate binning configuration, as 
       specified by binning name in constructor.

     - Add feature to weight() function to enforce special boundaries
       when interpolating a histogram representing a cumulative distribution function. 
       If so, lower-side bounds are forced to zero and upper-side bounds are
       forced to 1.0 instead of the default mirroring strategy


   o RooMsgService

     - Add new topic NumericIntegration

     - Show PROGRESS level messages by default


   o RooAbsSelfCachedReal

     - New base class for self-caching RooAbsReal objects analoguous
       to RooAbsSelfCachedPdf


   o RooCachedReal

     - New class to cache arbitrary RooAbsReal function objects,
       analogous to RooAbsCachedPdf


   o RooRealBinding

     - Add feature to save and restore values of input variables,
       used by RooRealIntegral to restore observable values after numeric
       integration to original values.


   o RooLinearMorph

     - New operator p.d.f class implementing using the algorithm described
       by Alex Read in NUM A 425 (1999) 357-369 'Linear interpolation of histograms'.
       This class implements a generalization for continuous p.d.f 


   o RooAbsRealLValue

     - Following changes in RooAbsLValue

 
   o RooHistFunc

     - Real-valued function modeled by external RooDataHist object, analoguous to RooHistPdf,
       but without normalization support and allowing negative histogram values


   o RooAbsCachedReal

     - New abstract base class for caching functions, analoguous to RooAbsCachedPdf.
       

   o RooFracRemainder

     - New dedicated helper class to calculate the remainder fraction of a RooAddPdf, i.e. 1-sum(i)x_i
       for a given RooArgSet x


   o RooCustomizer

     - Fix memory management issue for sterile use


   o RooAbsCategoryLValue

     - Follow changes in RooAbsLValue


   o RooNumCdf

     - Specialization of RooNumRunningInt to calculate running integrals of p.d.f.s:
       the running integral is by construction normalized to one exactly, taking out
       any possible imprecisions in the regular integral calculation and by imposing
       special constraints on the RooHistFunc that models the output so that the boundaries
       are constrained to exactly 0 and 1 when interpolation is used.


   o RooFFTConv

     - Fix bug in cache naming algorithm

     - Follow changes in RooAbsCachedPdf


   o RooChangeTracker

     - New special purpose object that tracks changes in a given set of variables, used
       to determine if cached p.d.fs in RooAbsCachedPdf and RooAbsCachedReal need to
       be recalculated due to parameter changes. In addition to valueDirty tracking,
       an explicit comparison can be made to stored reference values of variables,
       to avoid recalculation of expensive quantities in case a valueDirty is propagated
       even if the value did not change (this can e.g. happen when you step though
       a RooDataHist where usually only one of the observables changes value, but
       all observables propagate a valueDirty every time)


   o RooHist

     - Bug fix in makeResidual()


   o RooAbsReal

     - Fix small memory leak in createIntegral

     - Expand functionality of fillDataHist: optional correction for binVolume
       when filling, and optional progress indication.

     - Modify logEvalError() so that when cumulative logging for Minuit is disabled
       that messages are printed through the standard message logging service.

     - Modify error logging so that name of objects are stored in addition to 
       pointers so that delayed logging of errors of (cache) objects that no
       longer exists can be performed correctly.

     - Add virtual function preferredObservableScanOrder() to indicate preferred
       order in which multi-dimensional functions should be scanned into a 
       RooHistPdf, which may matter greatly for the performance of certain
       p.d.f.s like RooFFTConvPdf and RooLinearMorph

     - Add new function createRunningIntegral() which constructs for a given F(x,y) 
       a Int[xlo,x] F(x',y) dx. The default strategy is to construct the underlying
       integral with createIntegral() and adapt it with a RooCustomizer and a RooParamBinning
       to a running integral. In case it concerns a one-dimensional numeric running
       integral, the running integral is represented by a dedicated class RooNumRunningInt
       which scans the integrand and numerically integrates the scanned histogram


   o RooAbsCollection

     - Bug fix in nameFieldLength handling of print routine


   o RooAbsCachedPdf

     - Introduce explicitly the strategy that the cache contains the _normalized_ p.d.f. values,
       so that no postior normalization integral is required. This has the added advantages that
       the cache p.d.f can be instructed to consider itself normalized skipping an explicit
       normalization step in the RooHistPdf.

     - Add utility function getCachePdf() and getCacheHist() to retrieve cache p.d.f and histogram
       for a given choice of normalization set

     - Clean up structure of CacheElem nested class by making guts private and providing accessor
       function for derived CacheElem classes. Virtualize cache creation with a new member function 
       createCache that will allow derived classes to create a derived CacheElem.

     - Forward integration handling to cache pdf actually being used


   o RooDataHistSliceIter

     - Follow changes in RooDataHist for alternate binning 


   o RooRealMPFE

     - Follow changes in eval error logging in RooAbsReal


   o RooAbsPdf

     - Add createCdf() function to create cumulative distribution functions from p.d.f.s. This is 
       quite similar to RooAbsReal::createRunningIntegral() but with some c.d.f specific features
       related to constraints on normalization


   o RooAbsArg 

     - Fix bug in optimizeCacheMode()


   o RooBrentRootFinder

     - Improve error messaging through RooMsgService interface.


   o RooCmdArg

     - Expand payload from 2 to 3 strings


   o RooSimWSTool

     - Complete rewrite of RooSimPdfBuilder integrated with RooWorkspace for object storage.


   o RooNumRunningInt

     - New dedicated class to calculate running integral of any function that does not have
       an analytical integral implementation. This class scans such a function in a histogram
       and then numerically integrates the histogram. The filling of the histogram is performed
       adaptively using a recursion division strategy with a precision cutoff to save time
       of the filling of smooth functions in finely binned histograms


   o RooMultiCategory, RooSuperCategory

     - Minor tweak in name of proxies


   o RooAbsIntegrator

     - Deploy save and restore functionality of RooAbsFunc/RooRealBinding to restore observable
       values to prior values after an intergration step. 


   o RooMinuit

     - Fix gcc 4.3 compiler warning


   o RooWorkspace

     - Add bulk import() function taking a const RooArgSet instead of a RooAbsArg
 
     - Add RecycleConflictNodes() option to ignore conflicts and simply recycle internal
       nodes when a different external node is encountered.

     - Add new accessors catfunc() for category functions, arg() for generic RooAbsArgs,
       and funcArg() for fundamental arguments of any type.

     - Add separate section for category functions in Print()


   o RooHistPdf

     - Add option to declare contents unit normalized. When activated, the analytical
       integral is hardwired to 1. 

     - Add option to propagate cdfBoundaries mode to the underlying RooDataHist.


   o RooAbsOptTestStatistic

     - Optimize handling of empty rangeName specification (from Alfio)


   o RooSimultaneous

     - Tune proxy names

     - Make p.d.f return zero, in case index category is in state where no p.d.f is assigned,
       rather that assert(0)


   o LinkDef3.h, Module.mk

     - Add new class definitions

Import changes from development branch

==== Date: Wed Feb 20 22:33:28 2008 =====

   o RooRealSumPdf

     - Do _not_ use normalization of RooAbsPdf input components
       in numerator of RooRealSumPdf expression since it is 
       already explicitly occurring in denominator of RooRealSumPdf.
       (Fixes wrong normalization reported by Tristan)


   o RooObjCacheManager

     - Register owner of cache with each cache elememt to
       facilitate callbacks


   o RooAbsCacheElement

     - Add storage for pointer to owner of cache and
       supply setOwner() function


   o RooAbsPdf

     - Use RooObjCacheManager callback mechanism to zero
       'last used normalization' pointer in RooAbsPdf
       when the cache-owned object pointed is about
       to be deleted. 


   o RooAbsArg

     - Make crc32 function static


   o RooWorkspace

     - Add CodeRepo nested class that allows to store C++ code
       of RooAbsArg derived classes that are not in ROOT distribution
       but are contained in workspace. When reading any missing
       class, code is compiled on the fly allowing for transparent
       reading of workspace object from file. Code is found in
       location pointed to from TClass objects. Additional search
       path for declaration and implementation files can be provided
       to be able to handle non-trivial cases.

     - Add WSDir nested class that represents information contained
       in workspace as read-only TDirectory for easy interactive use. 
       Directory representation is created using makeDir() member function.


  o LinkDef3

     - Add nested classes in RooWorkspace

===== Date: Wed Mar 26 23:04:26 2008 =====

   o RooProdPdf

     - Fix typo in ctor documentaion

     - Implement getConstraints() function to retrieve constraint p.d.f terms from product
       expression given set of observables and set of parameters to be constrained.


   o RooMsgService

     - Add PROGRESS message level between INFO and WARNING

     - Add globalKill level for messages to be able to quickly eliminate all messages below
       a given level without interfering with the stream structore of RooMsgService


   o RooPrintable

     - Implement new printing interface with more details control over items printed trhough contents enum
       (multiple ORable options) and style of printing (inline, single line, (verbose) multiline) with style 
       enum (exclusive options). 

     - Introduce generic virtual functions for printing of name,title,value,arguments,
       and extras of each object. 

     - Each class can overload the default contents used for all printing
       uses (inline,verbose,standard) etc as well as the default printing style invoked by Print()


   o RooPlot,RooGenContext, RooAbsRealLValue,RooDataSet,RooNameSet,RooCustomizer, RooAbsGenContext, RooAddModel,
     RooFitResult,RooCurve,RooAbsAnaConv,RooHist,RooAbsReal,RooAbsCollection,RooAddPdf,RooTable,RooAbsData,

     RooThresholdCategory,RooAcceptReject,RooSuperCategory,RooEllipse,RooNumIntConfig,RooAbsCategory,RooListProxy,
     RooLinearVar,RooTreeData,RooTreeData

     - Update to new RooPrintable interface


   o RooGenContext,RooAbsGenContext,RooAddGenContext,RooProdGenContext,RooConvGenContext,RooSimGenContext

     - Implement attach() function to simplify management of changing parameters during lifetime of context


   o RooAbsRealLValue

     - Eliminate inFitRange() warning message as it is gives too many false warnings when used with
       parameterized ranges


   o RooCustomizer

     - Make owning of contents optional to simplify release of created components
     

   o RooAbsReal

     - Implement new evaluation error logging mechanism. Rather than passing zero p.d.f values, push error message with
       details on a static stack (if logging is enabled by e.g. RooMinuit). 

     - Augment functionality of createIntegral: explicitly allow integration over ranges with bounds parameterized in 
       in terms of other integrated observables. Integrals of this type are automatically recognized and cast
       as recursive integrals in case of >1-D integrals to integrate over requested phase space. 

     - Add createIntObj() helper function for above functionaliy.

     - Eliminate a lot of commented out debug code from createPlotProjection()

     - Modify fillHistogram(): when plot observables are cloned, explicitly interconnect clones again to facilitate
       proper plotting of N-D integrals with entangled parameterized ranges

     - Add ScaleFactor() argument to fillHistogram to control use of histogram density correction scale factor in Z-scale
       of filled histogram


   o RooProduction

     - Fix bug for persistence


   o RooRealMPFE

     - Extend client/server protocol with message to retrieve RooAbsReal evaluation error log from server side and
       merge with error log on client side


   o RooRealVar

     - Introduced concept of non-shared alternative binnings(ranges) required to accommodate RooParamBinning ranges
       that cannot be shared across instances because of their client/server connection to other objects in p.d.f
       expression trees. Modify setBinning to automatically recognize non-shareable binnings and divert those to
       non-shared alternative binning container.

     - Add setRange([const char*,] RooAbsReal&,RooAbsReal&) methods to simplify creation of parameterized ranges.


   o RooAbsArg

     - Introduce concept of owned components with addOwnedComponents() interface to be able to make any RooAbsArg
       object own any number of others. This can be used to simplify the memory management of object trees 

     - Introduce prohibitServerRedirect mode that will trigger fatal assert if any server redirect is attempted
       to thus configured object. Useful as debugging tool to track faulty copy constructors that leave clone
       object tree unintentionally connected to the original object tree.

     - Migrate fixed--name-field management tool from RooAbsReal to RooAbsArg. Used to accomplish regular
       formatting in RooAbsCollection::printStream.

     - Add concept of transient boolean attributes that are not tranferred on copy construction. Mostly useful
       for debugging.

     - Extend leafNodeServerList and treeNodeServerList to distinguish to types of leaf-nodes: strict leaf modes
       in the sense of the client-server tree structure and 'physical' leaf nodes that do not recurse into
       nodes that have isDerived()==kFalse. The latter corresponds to the original concept of leaf nodes / variables,
       which the former mode, a new addition, explicitly exposes any shape servers contained in parameterized
       ranges of variables.

     - Fix logic error in recursiveServerRedirect: do not recurse into nodes that are in the replacement list themselves.

     - Fix bug in printCompactTree(): value/shape clients were not always properly indicated.

     - Add getAllConstraints() method that finds all RooProdPdfs in expression trees and harvest constraints from all
       of these from the getConstraint() method


   o RooAbsPdf

     - Implement new evaluation error logging mechanism for negative p.d.f values and zero normalization integrals

     - Add Constrain(const RooArgSet& pars) and ExternalConstraints(const RooArgSet& pdfs) arguments to fitTo() method.
       The Constrain() method retrieves any constraints p.d.f. on parameters multiplied in any RooProdPdf in the normal 
       p.d.f expression and adds those to the likelihood that is minimized. Only constraints on the listed parameters
       will be picked up. Multiple constraints per parameter may exist. The ExternalConstrains() argument implements
       similar functionality except that provided external constraint p.d.f.s are added rather than internal constraints.

     - Fix potentially fatal bug in print statement in getContext()

     - Add new method createCdf() to create a cumulative distribution function from given p.d.f. Given a set of observables x, 
       the returned c.d.f is implemented in terms of a RooRealIntegral of p.d.f(x') over a parameterized range from [ 0 - x ].


   o Roo1DIntegrator

     - Improve error message


   o RooRealIntegral

     - Fix bug in calculation of shape dependencies on observables.

     - Add handling of dependencies of integral value on values of objects representing parameterized ranges of
       integrated observables.     


   o RooMCStudy

      - Add Constrain(const RooArgSet& pars) and ExternalConstraints(const RooArgSet& pdfs) arguments to constructor.
        In addition to passing these arguments to the fitTo() call of the fit stage, modify event generation as
        follows: instead of sampling events from 'static' generator p.d.f, sample value of constrained parameters
        from joint constraints p.d.f and sample observables at those parameter settings. Save the generator parameters
        for each toy as these change per toy. Change the pull calculation such that it uses the per-event truth values
        rather than the per-study truth value if constraints are used.


   o RooAddition

     - Fix bug in evaluate() related to persistence


   o RooMinuit

     - Enable/disable new evaluation error logging mechanism prior to and just after each MINUIT call.

     - Print logged error messages, if any, in glue function

   o RooGlobalFunc

     - Add definition of Scaling(),Constrain() and ExternalConstraints() helper functions 


   o RooUniformBinning
  
     - Remove dedicated print function as it output is identical to that of the generic print function in RooAbsBinningx

  
   o RooAbsBinning

     - Add virtual methods isParameterized(),lowBound() and highBound() to be to detect and analyze parameterized binnings
       through abstract interface

     - Add isShareable() method to be able to separate shareable and non-shareable binnings in RooRealVar.

     - Add insertHook() and removeHook() function to allow connection of possible proxies present in binning to
       owning RooAbsArg.


   o RooWorkspace

     - Improve code import facility by introducing a class->file mapping step in the CodeStore to correctly handle cases where 
       multiple classes are defined in a single file.

     - Add check that TClass interface actually yields file names.

     - Only require default constructor to be present for non-abstract classes. It should be there for abstract classes as
       well but current TClass::HasDefaultConstructor() method will not tell us.

   o RooTreeData

     - Improve renameVariable() method to not only rename the RooAbsArg branch buffer but also any TTree branches involved as well.
       While the tree branch names are generally invisible to the user, having branch names that are different from branch buffer names
       may cause branch naming conflicts in merge() that are not detectable as branch buffer naming conflicts.


   o RooParamBinning

     - New class implementing binning with low and high points defined by external RooAbsReal objects 


   o RooConstrainSum

     - Helper class for RooAbsPdf to represent likelihood of collection of constraint p.d.f.s.


==== Date: Fri Mar 28 10:04:57 2008 =====

   o RooRecursiveFraction

     - Helper function for RooAddPdf that calculates recursive fraction 
       f1*(1-f2)*(1-f3) from a given set of plain fractions


   o RooAddPdf

     - Add flag to ctor to optionally interpret fractions as recursive fractions.
       If activated it constructs the recursive fractions using RooRecursiveFraction
       from the original fractions


   o LinkDef3.h, Module.mk

     - Add new class RooRecursiveFraction

==== Date: Tue Apr  1 22:42:19 2008 ====

   o RooDataWeightedAverage

     - New implementation of RooAbsOptTestStatistics that calculates data weighted
       average of any RooAbsReal. This class serves as successor of RooDataProjBinding
       that no longer complies with new optimization scheme. 

   o RooRealBinding

   o RooChi2Var,RooNLLVar

     - Follow changes in base class


   o RooAbsReal

     - In plotOn() support binning flag in ProjWData(). Reimplement data-weighted projections
       using new RooDataWeightedAverage class instead of RooDataProjBinding which does not
       work with new generic function optimization scheme. 

     - Add support for NumCPU() argument
       in plotOn() to facilitate multi-processor calculation of projections. Extend NumCPU()
       argument to pass interleaving option in MP splitting mode of RooAbsTestStatistic

     - Move fixAddCoefNormalization() and fixAddCoefRange() from RooAbsPdf to RooAbsReal
  

   o RooAbsTestStatistic

     - Generalize functionality: allow RooAbsReals as input arguments instead of RooAbsPdfs only.
       Also add virtual globalNormalization() function that allows to apply a global normalization
       term after combinedValue() operation to facilitate functionality of RooDataWeightedAverage.

     - Add option to split data in multiprocessor mode in interleave mode instead of in bulk mode.
       Interleave mode is useful for parallel processing of histogram data where bulk partitions
       may not contain equal amount of non-zero data points leading to non-optimal load balancing
       between processes.


   o RooAbsPdf

     - Move fixAddCoefRange() and fixAddCoefNormalization to RooAbsReal to support operation of
       new generalized RooAbsTestStatistic
     

   o RooIntegrator1D

     - Use name() of RooAbsFunc() to clarify warning and error messages.


   o RooRealIntegral

     - Rename _operMode to _intOperMode to avoid shadowing of equally named data member in RooAbsArg

     - Fix bug in recursive printing

     - Fix bug in print()


   o RooGlobalFunc

     - Modify ProjWData() and NumCPU() helper functions with extra optional argument

       A separate list<EvalError> is now kept for each object that reports an error.
       In addition to the given error message a record is constructed of the proxy
       values at the time of reporting. 
 
     - In printEvalErrors() add option to restrict number of reported items per node.
       If number is zero, only number of errors per node is shown (without details)


   o RooRealMPFE
 
     - Adjust ReportErrors message to changes EvalError implementation in RooAbsReal.
 
     - Make sure to synchronize remote error logging state with state of parent process
       before each evaluate()


   o RooRealVar

     - Move printing of error from printValue() to printExtras()


   o RooNLLVar

     - Fix bug in setting of interleave parameter of base class in certain ctors

   o RooAbsCache

    - New abstract base class for cache objects associated with RooAbsArgs.
      Caches register themselves with the owning RooAbsArg and propagate
      all necessary state changes and meta information to objects in the cache


   o RooCacheManager

    - Concrete template implementation of RooAbsCache with an interface
      and functionality styled after RooNormListManager. The template class
      provide no special handling for cache contents that includes RooAbsArg
      objects and does not forward hook calls. It is thus mostly intended
      to cache basic types indexed on a normalization/integration configuration


   o RooObjCacheManager

    - Class derived from RooCacheManager<RooAbsCacheElement> that implements
      all proper call forwarding and handling of state and other meta information
      to RooAbsArg objects embedded in the cache elements. To facilitate this
      functionality the RooAbsCacheElement defines a pure virtual method
      containedArgs() that must be implemented to expose its contents to
      the cache manager. The default behavior on a serverRedirect hook is
      to sterilize the cache. OperMode changes are not forwarded by default
      to the cache contents as cached objects do not necessarily have the
      same operation mode (e.g. if the cache contains an integral of its owner).
      Any calls to optimizeCacheMode(), printCompactTreeHook(), and findConstantNodes()
      are forwarded. Moreover, optimizeCacheMode() calls are remembered and
      any objects inserted in the cache after such a call was received will be
      optimized upon insertion in the cache

   o RooAbsCacheElement

    - Abstract base class for objects to be managed by RooObjCacheManager. Each
      object must in addition to its payload implement the containedArgs()
      member function that exposes the RooAbsArg object content to the manager
      for processing. The argument passed to containedArgs() indicates the use
      case for the returned list of objects, allowing the cache payload to
      return different lists depending upon use. This is for most applications
      not required.


   o RooAbsCachedPdf

    - Abstract base class derived from RooAbsPdf for p.d.f.s that implement 
      value caching in a grid over the entire domain of the observables. 
      The base class implements the overall caching logistics and manages
      the RooDataHists and RooHistPdfs that respresent the cached contents.
      Derived classes must inputBaseName() defined a unique name prefix for
      all cache objects, actualObservales() and actualParameters() to
      determined the actual observables and parameters given a set of 
      available observables and fillCacheObject() which should fill the
      RooDataHist cache for a given obs/params configuration with the
      p.d.fs values.


   o RooAbsSelfCachedPdf

    - Abstract base class derived from RooAbsCachedPdf that implements
      all of the required logistics in RooCachedPdf and only require
      derived classes from RooAbsSelfCachedPdf to implement evaluate().
      Any class derived from RooAbsPdf can thus be trivially switched
      to derived from RooAbsSelfCachedPdf and gain the caching functionality.
      

   o RooCachedPdf

    - Concrete class derived from RooAbsCachedPdf that implements
      the caching of an externally provided p.d.f in the constructor.


   o RooFFTConvPdf

    - Concrete class derived from RooAbsCachedPdf that implement generic
      numeric convolution of two input p.d.f.s using FFT technique
      and convolution theorem. Actual FFTs are calculated by FFTW
      through TVirtualFFT interface in ROOT. Present implementation only supports 
      convolution in one dimension, but this will be extended later
      as there are no fundamental limitations in RooAbsCachedPdf nor FFTW.
 

   o RooHistPdf

    - Moved from RooFit to RooFitCore because it is used by caching classes


   o RooProdPdf

     - Use new RooObjCacheManager to store partial objects

     - Fix memory leak (already patched in 15.0.14h)


   o RooDataHist

     - Use new RooCacheManager template to cache partial bin volumes

     - Add new set(),setAllWeights() method to update current weight and all weights
       respectively, for use in cached p.d.f.s

     - Add sliceIterator() that iterates over all bins in a lower dimensional 
       slice of the dataset


   o RooDataHistSliceIter

    - Class derived from TIterator that implements the iteration
      over a slice in a reduced number of dimensions in a RooDataHist


   o RooMsgService

     - Speed up processing of debug streams in cases where no debug streams are active

     - add macros series oocoutX and oocxcoutX that allow to associate message with
       a different object than *this

   o RooRealBinding

     - Interface new setValue method that allows value to be set outside default
       domain, but inside given alternate named range. For use in numeric integrator
       bindings


   o RooAbsRealLValue

     - Add new inRange() method with range name specifier to check against chosen
       range instead of default range


   o RooCmdConfig

     - Fix dangling return pointer problem in decodeStringOnTheFly() method


   o RooNameSet

     - Fix bug in refoll()


   o RooChi2Var, RooNLLVar

     - Add processing of AddCoefRange() named argument


   o RooConvCoefVar

     - Hold p.d.f in proxy without value/shape state propagation to obtain
       correct dependency of RooConvCoefVar through separate set proxy
       with parameters that do have state propagation

     - In getAnalyticalIntegral() ask for integration coefficient specific
       to coefficient (following interface change in RooAbsAnaConv)


   o RooEfficiency

     - Follow interface change in RooCategoryProxy


   o RooAbsAnaConvPdf

    - Use new RooObjCacheManager to hold normalization and coefficient representations

    - Extend getCoefAnalyticalIntegral() interface so that each coefficient
      can have a separate integration configuration

    - Modify makeCoefVars() such that it constructs the RooConvCoefVars with
      actual dependents for each coefficients, rather than inserting dependencies
      of any of the coefficients in each coefficient. This logic requires support
      from the implementation class that is interface through a new member function
      coefVars()


   o RooAbsReal 

    - Add Boolean data member treeVar that indicates is value buffer is also
      branch buffer of a tree. This information is already present in the RooAbsReal
      but is relatively expensive to retrieve and is always needed in the inner
      loop of data set operations. This extra member significantly speeds up operations

    - Remove superfluous _norm[] token in name returned by integralNameSuffix() if 
      no normalization set is supplied.

    - Add a fillDataHist() method that fills a given RooDataHist with a sampling
      of the given function. Added for support of caching p.d.f.s


    - Downgrading warning on non-dependent projection variables in plotOn() to
      a debug level message

    - Remove function optimizeDirty(),doConstOpt(),undoConstOpt(),findCacheableBranches()
      findUnusedDatasetVariables() and findRedundantCacheServers() as part of reorganization
      of optimization functionality.


   o RooAbsCollection

    - Use iterator semantics instead of vector semantics to process RooLinkedList
      contents in assignment operator

    - Add utility function contentsString() returning stl string with names
      of contents


   o RooAddPdf

    - Rewrite cache management using new RooObjCacheManager that holds projection
      integrals, range integrals and supplemental normalization lists


   o RooAbsOptGoodnessOfFit

    - Improve handling of normalization ranges and reference ranges for test statistics
      containing RooAddPdfs. New named argument in fitTo() and RooNllVar::ctor() pass
      reference range for fractions in RooAddPdf components that do not have an explicit
      fixed definition already. Name all normalization ranges explicitly after the
      subrange to which the're applied to avoid name clashes and conflicts if multiple
      normalization ranges are involved.

    - Rewrite informational messages through RooMsgService

    - Implement new constOptimizeTestStatistic() function that signals all test statistic
      components of a RooAbsArg expression tree to perform their constant term optimization

    - Implement new optimizeCaching() driver function that changes default lazy-evaluation-with-caching
      scheme to test statistic scheme where only parameters objects propagate state changes and
      where all components that depend directly or indirectly on observables have lazy evaluation
      disabled. Changes to p.d.f objects are delegated to RooAbsPdf::optimizeCacheMode(). Changes
      to dataset are delegated to RooAbsData::optimizeReadingWithCaching()

    - Implement new optimizeConstantTerms() function that is back end for constOptimizeTestStatistic
      implementation. 


  o RooAICRegistry, RooNormSetCache

    - Remove tracking of allocation cycles of RooArgSets as this scheme is superseded by
      memory pool mechanism for RooArgSet allocation


  o RooMappedCategory

    - Follow interface change in RooCategoryProxy.


  o RooRealMPFE

    - Follow reorganization of optimization functionality: implement new constOptimizeTestStatistic
      function for forwarding to slave processes.


  o RooRealVar

    - Add new setVal() function with range name to facilite setting of values that are outside
      default range, but inside specified alternate range. Needed for numeric integration and
      certain RooAddPdf coefficient projection.


  o RooAbsArg

    - Make state management functions public [is/set][Value/ShapeDirty](), setOperMode90
  
    - Add static _flipAClean boolean to support setACleanAdirty() static method.

    - Implement mechanism for registration of cache objects with base class RooAbsCache.
      Forward all calls to operModeHook(), redirectServersHook(), optimizeCacheMode()
      and printCompactTreeHook() to all caches for further processing
   
    - Define constOptimize() function and provide default implementation that forwards
      to all servers 

    - Implement optimizeCacheMode() function that puts expression tree in optimized
      caching for test-statistics operations (only cache/lazy evaluate nodes that
      do not (indirectly) depend on observables

    - Implement findConstantNodes() function that identifies all nodes that depend
      exclusively on constant observables and >0 observables that are eligible
      for precalculation and caching in test statistics operations by 
      RooAbsOptTestStatistic::optimizeConstantTerms()

    - Define constOptimizeTestStatistics that signal an expression tree that any
      embedded test statistic objects should perform their constant term optimization.
      Default implementation in RooAbsArg forwards call to all servers.


  o RooAbsPdf

    - Use new RooObjCacheManager to manage normalization integrals cache.

    - Process new SumCoefRange() option in fitTo() that sets the coeffient
      interpretation range for all embedded RooAddPdf objects of which
      the interpretation range was not explicitly set

    - Extend interface of fixAddCoefNormalizationSet(): add extra argument
      that controls if AddCoef normalization set are forcibly overruled
      for objects that already have an explicit range setting.

  
   o RooRealIntegral 

    - Add some informational messaging through RooMsgService, rewrite existing ones

    - Speed up numeric summations by precreating the involved RooSuperCategory
      in the ctor rather than in evaluate().

    - Fix bug in dependency insertion: explicitly require servers to be value
      server to avoid pulling in fake dependents.
    
    - Remove obsolete data members

    - Implement new setACleanADirty() function that atomically flips state of
      all AClean objects to ADirty for the duration of the integration step.
      Replaces the much more expensive prepareACleanFunc() that did this
      only for the objects involved.

    - Process factorizing terms in integral only if the list is not empty

    - Process Jacobian terms in integral only if the list is not empty


  o RooAddGenContext

   - Adapt to cache management chanches in RooAddPdf


  o RooNumIntFactory

   - Use STL classes for internal memory management


  o RooSetProxyy

   - Implement operator new() and operator() delete as required because
     RooArgSet implements them 


  o RooAbsGoodnessOfFit

   - Store and forward AddCoefRange information for embedded RooAddPdf objects

   - Implement constOptimizeTestStatistic() and forward to components


  o RooErrorVar

   - Follow inRange() interface change in RooAbsRealLValue


  o RooConvGenContext

    - Adapt code to make it work with both RooAbsAnaConv objects and
      the newly introduced RooFFTConvPdf


  o RooMinuit

    - Follow reorganization of optimization functionality


  o RooProjectedPdf

    - Store projection using new RooObjCacheManager


  o RooGlobalFunc

    - Add RooFit::SumCoefRange() named argument for RooAbsPdf::fitTo() 
      and RooNLLVar::ctor() and RooChi2Var::ctor()


  o RooClassFactory

    - Extend existing makePdf(),makeFunction and makeClass() functions
      to also accept RooAbsCategory arguments, to accept an optional string
      inserted as the return value expression inserted in the 
      evaluate() method of the class created, as well as as option string
      specifying one or more analytical integrations of the given function
      expression that will be advertised in the generated getAnalyticalIntegral()
      code and implemented in the generated analyticalIntegral() code

    - Add makeAndCompileFunction() and makeAndCompilePdf methods that
      generate the code and immediate compile it through ROOTs ACliC interface.
      These functions have a simpler interface because the list of arguments
      of the function to be created can be specified as a const RooArgSet&
      rather than a string with a list of names, thus making it easier
      for on-the-fly definition of compiled objects.

    - Add defineFunction() and definePdf() methods define and compile
      a function/pdf using the above functions and immediately instantiate
      an object of the given type passing the specified RooArgSet arguments
      to the constructor of the object. These functions make a compiled
      equivalent of RooFormulaVar based on the TFormula interpreter, i.e.

           RooAbsReal* f = new RooFormulaVar("f","D(1-2w)",RooArgSet(D,w)) ;

      becomes
       
           RooAbsReal* f = RooClassFactory::defineFunction("f","D(1-2w)",RooArgSet(D,w)) ;

   
  o RooAbsCategory

   - Add Boolean data member treeVar that indicates is value buffer is also
     branch buffer of a tree. This information is already present in the RooAbsReal
     but is relatively expensive to retrieve and is always needed in the inner
     loop of data set operations. This extra member significantly speeds up operations

   - Construct explit clean name for TBranch name if node is cached, equivalent
     to what is done in RooAbsReal. Needed because new constOptimizer can also
     cache RooAbsCategory objects


  o RooArgSet

   - Implement operator new() and operator delete() to implement memory pool scheme
     for RooArgSets. The goal of this implementation is to insure that two RooArgSet
     pointers are _never_ the same. This allows to RooNormSet cache manager to safely
     and quickly index integration and normalization configurations by evaluating
     the contents of a RooArgSet only the first time it sees it.


  o RooSimultaneous

   - Implement caching of partial integrals using new RooObjCacheManager

   - Following interface change in RooCategoryProxy ;


  o RooAbsData

   - Defined pure virtual methods optimizeReadingWithCache() and allClientsCached()


  o RooTreeData

   - Implement optimizeReadingWithCache() which determines given a p.d.f to be
     evaluated and a list of the nodes that are cached for it, which observables
     in the dataset are no longer required because they are either not an observable
     of the p.d.f, or they exclusively feed nodes that are cached. Reading of these
     observables is disabled through SetBranchStatus().
  
   - Move allClientsCached() utility function here from RooAbsReal.


  o RooCategoryProxy

   - Remove const char*() conversion operator in favor of a const char* label() method
     to remove possibly ambiguities in C++ math expressions involving category proxies.


  o LinkDef3.h

   - Add newly defined classes

    - Make resetNumCall() const

  o RooAbsIntegrator

    - Add calculate() method that wrape integral() between
      profiling code the track the number of integrand
      function calls

    RooSegmentedIntegrator2D,RooMCIntegrator

   - Change interface to take RooNumIntConfig class instead
     of now deprecated RooIntegratorConfig class

   - Add member function that advertise capability of the integrator:
     canIntegrate1D,2D,ND,OpenEnded()

  o RooAbsReal

   - Change normalization integral management classes
     (createIntegral(), (set)defaultIntegratorConfig(),
     (set)specialIntegratorConfig()) to work with new
     RooNumIntConfig class.

  o RooArgSet

   - Add new convenience functions get/setRealValue(),
     get/setCatLabel/Index(), get/setStringValue() to
     manage common content of RooArgSet.

  o RooConvCoefVar, RooConvGenContext

   - Support class name change RooConvolutedPdf -> RooAbsAnaConfPdf

  o RooCustomizer

   - Add function setCloneBrancSet() that allows to specify
     an external set that takes ownership of the cloned branch
     nodes so that customized objects can live beyond the lifetime
     of the RooCustomizer instance

  o RooImproperIntegrator1D

   - Add code to handle limit scenario changes (closed to open ended
     and vice versa) on the fly

  o RooIntegrator1D

   - Add fixSteps option to terminate integral calculation after
     fixed number of steps w/o extrapolation. This is more robust
     for certain types of integrals

  o RooRealIntegral

   - Change interface to take RooNumIntConfig class instead of
     RooIntegratorConfig class

   - Delegate instantiation of numeric integration engines to
     new class RooNumIntFactory

  o RooNumIntConfig

   - New class to store configuration of numeric integator engines.
     This class has a brief common section with common properties
     like absolute and relative precision convergence criteria,
     and a section with implementation specific details for each
     engine in the form of a RooArgSet. The default settings for
     each existing engine are automatically added to the defaultConfig()
     instance during run-time initialization

  o RooNumIntFactory

   - Factory class for numeric integration engines. Each existing
     integrator engine automatically registers with the factory
     stating its capabilities (1D,2D,ND / Open-ended). The
     createIntegrator() function instantiates an integrator
     appropriate for a given problem. In case more than one
     integration engine can solve the given problem the (user
     changable) information in the RooNumIntConfig passed along
     with the call is used.

  o RooGaussKronrodIntegrator1D

   - New integrator engine based on Gaussian quadrature techniques.
     This implementation, taken from GSL 1.5 implements the Gauss-Kronrod
     techniques where the error on the integral is take from the difference
     between the Gauss and Kronrod techniques. These techniques share common
     sampling points allowing to calculate the error without additional cost.
     This integrator applies the 10,21,43, and 87 point rules in succession
     until the desired accuracy is reached. Open-ended integrals are
     automatically handled through a x -> 1/x coordinate transformation

  o RooAdaptiveGaussKronrodIntegrator1D

   - New integrator engine based on Gaussian quadrature techniques.
     This implementation, taken from GSL 1.5 implements the Gauss-Kronrod
     techniques where the error on the integral is take from the difference
     between the Gauss and Kronrod techniques. These techniques share common
     sampling points allowing to calculate the error without additional cost.
     This integrator applies the 10,21,31,41,51 or 61 point rule and
     recursively subdivides the integration domain until the desired accuracy
     is reached. For integrands with integrable singulaties the Wynn epsilon
     rule can be selected to speed up the converges of these integrals. Open
     ended integrals are automatically handles through a x -> 1/x
     coordinate transformation

  o RooNumConvPdf

    - New operator PDF class that implements numeric convolution of
      any two PDFs. The calculation of the convolution integrand
      is implemented in the auxiliary class RooConvIntegrandBinding,
      which in turn can be integrated with any 1-D numeric integration
      engine. The default integration method for convolution integrals
      is the adaptive Gauss-Kronrod method, which appears to give the
      most stable results. By default the integration is performed
      from -inf to +inf, but can optionally be restricted to a sliding
      window using the setConvolutionWindow class, useful for relatively
      narrow resolution PDFs.

  o RooAbsAnaConvPdf

    - New name of RooConvolutedPdf to clearly distinguish its functionality
      from RooNumConvPdf

  This round of updates achieves two major goals

    - Large (O(10-100)) speedup in handling of very
      complex PDFS (>10000 nodes) by pervasive use
      of self-expanding hash tables

    - Fix outstanding problems with RooProdPdf
      through new strategy to deal with cached
      objects in cloning/server redirect operations

  There is also a handful of minor fixes

  ------------------------------------------------

  o RooSetPair

    - New auxiliary class to store pair of RooArgSet pointers


  o Roo1DTable

    - Don't fill entries with zero weight


  o RooAbsArg

    - Add optional 2nd arg to printCompactTree() to store
      output to file


  o RooAbsCollection

    - Initialize RooLinkedLists with hashing size threshold of 43



  o RooAbsGoodnessOfFit, RooAbsOptGoodnessOfFit, RooProdPdf

    - Follow changes in printCompactTree() syntax



  o RooAbsOptGoodnessOfFit

    - Remove all methods that implement dirty state optimization
      and constant term caching (migration to RooAbsReal)


  o RooAbsReal

    - Various fixes in plotAsymOn fix plotting of asymmetries
      in conjunction with ProjWData() and Slice()

    - Add methods that implement dirty state optimization
      and constant term caching (migration from RooAbsOptGoodnessOfFit)


  o RooDataProjBinding

    - Remove some old debug code


  o RooHashTable

    - New constructor option allow to choose hashing by name,
      pointer or objects Hash() value

    - Switch to using TMath::Hash() fast hashing method
      using 'especially selected random numbers' (!)

    - Add kludgy support for storage of RooLinkedListElem
      and RooSetPair objects, which do not inherit from TObject.

      (A full redesign of RooLinkedList and RooHashTable is needed
       at some point)


  o RooHist

    - Fix print statement


  o RooHistError

    - Lower (n,m) threshold for calculation of approximate binomial
      error to avoid factorial overflow problems.


  o RooLinkedList

    - Introduce automatically activated hashing by name and pointer
      to speed up handling of long lists beyond size threshold
      given in ctor (zero threshold disables this features)

    - Automatically rehash tables when #entries becomes greater
      than hash table size


  o RooNameSet

    - Sort contents upon insertion. This fixes broken operator==
      for certain set comparisons


  o RooNormListManager

    - Add support for 'sterile' operation. If contents is sterilized
      via new sterilize() member function or use of sterile copy
      ctor RooNormSetCache information is retained (and thus
      ordering and slot indeces used by client classes) but
      stored contents associated with given iset/nset pairs
      is deleted. A 'setNormList()' call that maps to a
      sterilized slot will recycle that slot. Optional new argument
      in getNormList will tell client that requested information
      has been sterilized rather than not being there.


  o RooNormSetCache

    - Store set pair information in hash table of RooSetPair objects
      rather than two fixed size arrays of RooArgSet pointers.
      This greatly improves lookup speed (indexed by set pointers)
      and automatically expands the capacity of the set cache
      as is needed for very complex fits.


  o RooProdPdf

    - Abandon strategy to forward redirectServer requests to
      cached product configurations. This strategy has turned
      out to be flawed as insufficient information is available
      in the redirectServers context to do the right thing
      under all circumstances. Invocation of redirectServerHook()
      will now sterilize the cache, using new RooNormListManager
      feature

    - Modify getAnalyticalIntegralWN(), which looks up cached
      product configurations by index to recognize sterilized
      entries. If such an entry is encountered, it is reconstituted
      on the fly.


  o RooRealIntegral

    - Store owned clones of factorizing observables instead of linking
      to instances provided in ctor as ownership related of those
      turns out not to be well defined.


  o RooRefCountedList

    - Set hashing threshold of underlying RooLinkedList at 17


  o RooSimPdfBuilder

    - Increase buffer sizes of RooStringVars in set returned by
      createProtoBuildConfig() to accomodate requests for ever
      more complex pdf configurations.

       * resetCache() clears the existing cache
       * setArgStatus() disables reading of given args from tree

  o New class RooAbsGoodnessOfFit

    - Abstract base class for goodness-of-fit variables.
      A goodness-of-fit is any quantity calculated from a PDF
      and a dataset. This class orgamizes parallelization over multiple
      CPUs and calculation of GOFs from simulatenous PDFs.

  o New class RooAbsOptGoodnessOfFit

    - Abstract base class for goodness-of-fit variables
      that calculate the PDF value at each data point in the
      given dataset. It implements various optimizations:
      caching of constant terms, elimination of unused variables etc.

  o RooAbsPdf

    - Deploy new normalization integral manager RooNormManager
      to cache multiple normalization integrals for a PDF.
      This greatly increases the efficiency for certain situations
      where PDFs are alternatingly called with 2 or more different
      normalization choices

      RooNormListManager

    - Deprecate use of RooResolutionModel::getNormSpecial. No longer needed.

  o RooCustomizer

    - Fix memory leak

  o RooDataHist

    - Add lo/hi Error associated with each bin. Default implementation
      returns poisson errors. Error is return by weightError().

    - New set() function allows user to override poisson errors

  o RooLinTransBinning

    - Add description

  o RooLinkedListElem

    - Add description

  o RooLinkedListIter

    - Add description

  o New class RooMPSentinel

    - New class to keep track of server processes started for
      parallelized goodness-of-fit calculations. On linux
      hosts, these processes don't exit when the parent process
      exits. This class sends termination signals when this
      singleton class is deleted

  o RooMath

    - Activate CERF disk caching by default

  o New class RooMinuit

    - New seamless interface between RooFit objects and MINUIT
      Class propagates information forth and back between RooAbsArg
      objects and minuits internal memory buffer (e.g. parameter
      values, errors, step sizes, constant status)

    - This class minimizes any RooAbsReal function (doesn't need to
      be a NLL or Chi2)

  o Removed class RooNLLBinding

    - Obsolete after introduction of RooNLLVar

  o New class RooNLLVar

    - Implementation for NLL of RooAbsOptGoodnessOfFit

  o RooNameSet

    - Fix memory leak

  o New class RooNormManager

    - New manager class for normalization/projection integrals for PDFs
      This class matches RooArgSet pointer pairs to the integration
      and normalization sets to previously registered integrals.
      Multiple pointer pairs can point to the same integral (e.g.
      pointer to different RooArgSets with the same contents) and
      multiple integrals can be cached. This class doesn't create
      the normalization integrals. It merely indicates if it has
      one or not, and leaves it up to the owning class to create
      and register new normalizations


  o New class RooNormListManager

    - Similar to RooNormManager, except that RooArgLists of normalization
      integrals are caches instead of single integrals

  o RooNormSetCache

    - Rework functionality. This class, used by RooNorm(List)Manager
      manages multiple redundant RooArgSet pointer pairs that represent
      the same projection/normalization configuration

  o RooProdPdf

    - Almost complete rewrite in terms of RooNormListManager


  o RooRealConstant

    - Minor const changes

  o RooRealIntegral

    - Streamline iterator use: Create various interator in ctor
      and reuse them in evaluate() instead of creating and deleting
      them on the fly

  o New class RooRealMPFE

    - Front end for MultiProcessor calculations. Class RooRealMPFE
      takes a RooAbsReal as argument and calculates it in separate
      process. Calculations can be started asynchronously with
      the calculate() call. The rest of the interface (and behaviour)
      is identical to that of the original RooAbsReal.

  o RooResolutionModel

    - Deprecate getNormSpecial - superceded by RooNormManager

  o RooSetProxy

    - Implement addClone(const RooAbsCollection&,...)

  o Removed class RooSimFitContext

    - Obsolete - replaced by RooMinuit/RooNLLVar

  o RooSimGenContext

    - Fix memory leak

  o RooSimultaneous

    - remove obsolete fitContext() method

  o RooTreeData

    - Reimplement caching. Cached functions are now stored in
      a separate tree in the dataset. Main benefit of the new
      implementation is that caches can efficiently be reset
      and refilled on the fly

  o makedocs

    - Add stanzas for new tutorial macros

  o RooAbsCollection

    - add overlaps() function to check for common elements in to collections

  o RooAbsReal

    - New feature: Allow sliced variables to appear in projected data set.
      If so, a reduced dataset is created on the fly consisting of only
      events that are part of the current slice. This saves the caller
      the work of creating a projection dataset for the subset of events
      of the plotted slice

    - Bug fix: before activating coefficient projection transformation,
      check if transformation is not identity (e.g. from (A,B) -> (B,A))

  o RooRealIntegral

    - Make RooIntegratorConfig* pointer data member non-const. This gives
      some trouble in the Streamer() generated by older root versions

  o RooSimPdfBuilder

    - Add buildConfig() methods that take a RooArgSet of dependents instead
      of a dataset

  o RooSimultaneous

    - Overhaul of plotting interface. Now require that a projection dataset
      with (at least) the components of the index category is always given,
      even if only a single state is plotted.

      This allows a consistent treatment of normalization in slice plotting
      w.r.t to regular PDFs: the plotted PDF is multiplied by the fraction
      of projected data events selected in the plotted slice.

      Substantial work on index projection engine now allows all possible
      slices, such as a slice in only one of the components of a composite
      index category.

      Implement 'auto-reduction' feature on projection dataset, as is done
      in RooAbsReal::plotOn. In addition also remove index category-related
      columns of dataset before passing it on the the RooAddPdf plot variable
      This eliminates some fake warning messages

      Major improvement in slicing/projection info messages

 o RooAbsArg

   - Keep track of cloning with attributes. add isCloneOf()
     method to test if objects are clones

 o RooAbsCollection

   - Implement check of 'unique-name rule' in snapshot() method.
     Disabled for the moment as we violate this rule in benign ways
     in several places in the core code. This needs to be fixed first

 o RooAbsPdf

   - Add methods to specify numerical integrator configuration to be
     used in normalization
     There is one global default configuration (RooIntegratorConfig object)
     and each PDF can optionally have a private configuration that
     overrules the default one.

 o RooAddPdf

   - Add on-the-fly transformations for coefficients between
     normalization sets.  Users can now specify a
     'reference normalization' via fixCoefNormalization() in
     which the fractions will always be interpreted.
     If no such reference set is specified the default behaviour
     will prevail: the interpretation depends on the current normalization.

 o RooAbsReal

   - Change plotOn() such that when a PDF containing RooAddPdfs
     is projected with data, an appropriate reference normalization
     is set for each, if no user-supplied reference normalization
     was set. This ensures intuitive behaviour of plotOn() for RooAddPdfs

   - Add easy-to-use wrapper function for createProjection()

 o RooErrorVar

   - Add readFromStream/writToStream()

   - Declare fundamental

 o RooImproperIntegrator1D,RooIntegrator1D

   - Add constructors from RooIntegratorConfig

 o RooMCIntegrator

   - Add constructor from RooIntegratorConfig

   - Make #iterations and #call per iteration for grid refinement
     and integration configurable parameters

 o RooProdPdf

   - Complete rewrite. Now _all_ permutations of integration/normalization
     are correctly performed. New implementation uses a product
     of partial integrals created with pdf->createIntegral()

 o RooRealIntegral

   - Add optional RooIntegratorConfig to ctor and pass to numerical
     integrator ctors in various places

 o RooSetProxy

   - Fix server management for owning set proxies

 o Many classes

   - Anticipate potential failure of snapshot() due to unique-name
     rule enforcement and handle such situations appropriately

      object name string. In such case the object/attribute
      of the last added object will be returned.

  o RooRealIntegral

    - Overload printToStream() to print out basis function details
      in verbose mode

  o RooTreeData

  o RooRealIntegral

    - Introduce LValue detection in tree structure analysis.

      An iterative algorithm determines if there is a non-empty
      set of LValue branch nodes suitable for analytical integration
      and a set of leaf nodes to be integrated, that exclusively
      relate to each other (i.e. set of leafs serves only exactly one
      element of the set of LV branches; LV branches only depend on
      that set of leafs). If such sets can be found, the LV branches
      are substituted for the leafs in the list of dependents to be
      integrated.

      Actual use of these LV branches in analytical integration
      still depends on capability of integrated function. If not,
      numerical integration will be performed on LValue.

      Caveats: currently the algorithm does not optimize scenarios
      like 'server a -> LVnodes (A,B), server b ->LVnodes(A,B), i.e.
      multi-dimensional coordinate rotations. Although the
      iterative algorithm could easily identify the potential replacement
      (a,b) -> (A,B), such substitutions would have to be reviewed
      after interaction with the integrated functions' getAnalyticalIntl().
      If it turns out the function can only analytically integrate A or B
      but not both, the entire substitution would have to be backed out
      as an integral over (A,a,b) or (B,a,b) has a redundant dimension.

  o RooArgSet,RooArgList

    - Add ctor from TCollection. RooArgSet ctor will skips and warns about
      eventual duplicate entries by name.

  o RooAbsPdf

    - Remove obsolete fitTo(TH1*,...) dummy entry point.

   Major cleanup in integration of normalization functions

   Miscellaneous small improvements and fixes

   o Roo1DTable

     - Add get(),getFrac() methods to retrieve contents

   o RooAbsCollection

     - Add selectCommon() method to create new collection
       containing args common to two sets

   o RooAbsData

     - Minor const-correctness changes

   o RooAbsReal

     - Rearrangement of getAnalyticalIntegral/analyticalIntegral entry points.
       Both functions now exist with and without a 'const RooArgSet* normSet'
       The functions with normSet are used by RooRealIntegral, and its default
       implementation handle the pass-through scenario (code 0 = getVal(normSet))
       and defers other codes to the non-normSet variant.

       Simple PDFs should implement the non-normSet variants, as they used
       to do sofar, except they no longer should (or are able to) process
       the passthrough scenario.

       Advanced PDFs such as RooAdd,ProdPdf, RooConvolutedPdf that implement
       complex integration schemes that depend on the exact normSet configuration
       reimplement the getAI,aI functions with normSet.

   o RooResolutionModel, RooAddModel

     - Implement (or forward in case of RooAddModel) new getNormSpecial method.
       This function is identical in functionality to RooAbsPdf::getNorm()
       except that it caches a separate copy of the normalization integral.

       This member is introduced for the benefit of RooConvolutedPdf::analyticalIntegral
       which, in case of a normalized integration, alternatingly calls two different
       normalizations. In the original single cache code, this would lead to
       100% caching failure and 300% slowdown of the code. getNormSpecial is
       protected for access by RooConvolutedPdf only.

   o RooAddPdf,RooProdPdf,RooSimultaneous,RooConvolutedPdf

     - Re-implement distributed analytic integration bookkeeping using
       the auxiliary RooAICRegistry class, which keeps track of multiple
       analytical integration codes (hence AIC)

   o RooAICRegistry

     - New auxiliary class to faciliate the management of distributed analytic
       integration.

   o RooArgSet

     - Minor printing fix

   o RooConvolutedPdf

     - Complete rewrite of handling of analytical integrations. For RCP objects
       analytical integrations are not all necesarily analytic, but include
       integrations deferred to convolution objcts. Analytical integrations
       are split off for coefficient terms. Complete double bookkeeping introduced
       for 'integration' part of analytic integration and 'normalization' part
       of integration, each of which can have a different argSet to defer
       to the convolution objects and a different coefficient analytical integration
       code. Current implementation is believed to be complete.

   o RooFormulaVar

     - Follow signature change of getAnalyticalIntegral/analyticalIntegral

   o RooMath

     - Implement file cacheing scheme for complex error function lookup table.
       To invoke persistent caching, call RooMath::cacheCERF(kTRUE) prior to
       use

   o RooRealAnalytic

     - Store and forward normalization set to analyticalIntegral call of
       bound RooAbsReal

   o RooSimultanous

     - Implement new plotOn() method, taking a dataSet which can correctly
       project a RooSimultaneous. The code is mostly copied from RooAbsReal::
       plotOn, except that the plotted pdf is constructed as a RooAddPdf
       of the RooSimultaneous components, weighted by the fractions found
       in the passed dataset

   o RooTreeData

     - Small const-correctness fixes

  o All RooAbsArg derived classes

    - Change clone() to clone(const char* newname=0) to facilitate cloning with alternate names.

  o RooAbsArg

    - Add another layer to link management: operMode. If operMode=auto, all behaves
      as before. If operMode=AClean, the arg assumes the cache is always clean and
      getValueDirty() will always return false. If operMode=ADirty, the arg assumes
      the cache is always dirty and isValueDirty will always return true.

      The ADirty and AClean modes are used by the optimizer in the fit context
      to shut down link management (and save time) for cases where the arg is
      always dirty after a dirty state propagation from one of the dependents.
      The AClean mode is used similarly for args that are cached in the dataset

      The setOperMode() member is protected as care should be taken in switching modes.
      It is the callers responsability to ensure that the claimed state (especially
      in case of AClean) is indeed correct.

    - Split setValueDirty(Bool_t flag) in setValueDirty() and clearValueDirty().
      The latter is trivial and can be inlined to save time.

    - redirectServers() now has an optional nameChange flag that allows to reconnect
      to servers with different names. If the option is enabled, a link will be reconnected
      to the server with a 'ORIGNAME:<servername>' attribute instead of a server with <servername>
      This feature is used by RooPdfCustomizer.

    - Added recursive printDirty() member that listed dirty state of arg and all its servers.

    - Add sorting capability by implementing IsSortable() and CompareTo() members.
      Sorting will result in alphabetical ordering by object name.

 o RooAbsCategory

    - Change tree attachement: store both label and index fields in tree instead of
      just the index field. Looking up the corresponding label turns out to be rather
      expensive, especially if many state are defined.

    - The postTreeLoadHook() mechanism that formerly implemented the index lookup
      has been abandoned completely (save 1 virtual function call per data set load).

 o RooAbsPdf

    - Change function call structure of eval tracing a bit to reduce the number
      of calls per trace from virtual calls to 1 concrete call.

    - In syncNormalization, if the data sets are different, first check if they
      also have a different contents before processing the change. (Save multiple
      identical normalization calculations for cases were a resolution model is
      shared by >1 RooConvolutedPdf. (WVE Caveat: this has some problems: code will
      die if cached data set is deleted before pdf. Will fix this soon)

      Install pre- and postSyncNormalizationHook functions that can be used to customize
      the call. Used by RooConvolutedPdf to create/update dummy data sets used to
      push down partial integrations to the convolution integrals.

    - Move nLogLikelihood to RooFitContext

 o RooAbsReal

    - in attachToTree(), mangle name of object in tree to exclude math symbols that
      are interpreted by root in certain circumstances

 o RooAddModel

    - Store coef and proxy iterators in class instead of creating them on the fly each
      time in evaluate()

    - Release ownership of proxied resolution models in the copy constructor. If the
      AddModel is copied, the proxied components will be owned by the list created
      by RooArgSet::snapshot().

    - Include name of AddModel owner in component resolution model to avoid multiple
      identically named object in certain PDF configurations

    - Export 'master list' of combined normalization leaf node servers of all components.
      The convolutedPdf needs this for it's own dependency calculation

 o RooArgSet

    - Add silent option to remove()

 o RooCatType

    - Store name in char[] instead of in TNamed::fName (a TString) so that
      the name can be attached to a Tree. (A TString is not a TObject)

 o RooConvolutedPdf

    - Push integration of all dependents that do not overlap with the coefficients
      to the convolution integrals, instead of just the convolution variable

 o RooDataSet

    - Add new constructor that allows to specify the cut as a RooFormulaVar object
      instead of a string. This allows to cut on function arguments that are not
      part of the data set

    - Allow to switch off dirty state propagation after a row-load operation
      (can be used in certain optimization scenarios)

 o RooFitContext

    - Add option to not clone either dataset or pdf on construction

    - Remove non-RooRealVar parameters from master parameter list to prevent that
      MINUIT chokes on them

    - Sort minuit parameter list alphabetically

    - Add cache optimization option, which shuts down all link management for the
      all pdf value components (not normalization). This can save a significant amount
      of time, especially for very complex PDFs as the number dirty propagations scales
      with the square of the number of nodes. Use newly introduces AClean and ADirty
      modes to ensure proper evaluation of PDF nodes

    - Add option to execute migrad with 'strategy 0', which skips the evaluation of
      the error matrix. (Saves time if you do that later with HESSE anyway)

    - Move nLoglikelihood() function from RooAbsPdf to here.

    - Improve readability of messages in fitting in log-mode: print on screen only value
      and name of parameters that change instead of dumping all their values all the time.
      The old format has been retained in the log file, to allow automated processing of such files.

 o RooFormulaVar

    - Also update _origList on a serverRedirect

    - Export ok() function of RooFormula (indicates if expression compiled ok)

 o RooMath

   - Add fast, interpolated, complex error function. Upon first use separate lookup tables
     are filled for the im and re part of the complex error function. New functions will
     do a 2nd or 3rd order 2D interpolation (depending on z) of the lookup table for either
     the re part, the im part or both. Precision is better that 1e-6 in ~99% of covered
     phase space. Imprecise regions are in problematic part of cErf where giant fluctuations
     occur. Typical likelihood calculated with interpolated cErf agrees in the first 10
     significant digits. Interpolation function is ~3.5 times faster than original CWERF
     implementation, when only 1 component (im/re) of cErf is needed (most cases).

     Interpolation function taken from Numerical Recipes and further optimized for
     fixed grid assumption

 o RooMappedCategory

    - Clone also MapCatEntries in RooMappedCategory copy ctor

 o RooProdPdf

    - Store coef and proxy iterators in class, instead of instantiating them on the fly
      in evaluate()

    - Add optional cutoff parameter. If running PDF product goes below cutoff, product
      calculation is terminated (default value=0, very small values like 1e-15 can be
      benificial in case of wide window calculations a Gaussian + something flattish)

 o RooRealIntegral

    - Allow and perform integration over variables that input function doesn't depend
      on (multiply integral by product of ranges of such variables)

 o RooResolutionModel

    - In convolution(): append name of owner to convolution, to avoid non-identical
      convolutions with the same name in certain PDF configurations

    - Forward redirectServers to basis function

 o RooSimultaneous

    - Overload fitTo() to create a RooSimFitContext instead of a RooFitContext
      which allows certain additional optimizations specific to RooSimultaneous

    - Normalize by the number of registered PDFs instead of the number of types
      defined by the index category (allows to to partial fits)

 o RooStreamParser

    - Take '}' and ';' out of the default punctuation list so that RooSuperCategory
      state names do not get broken up into multiple tokens

 o RooThresholdCategory

    - New category class that applies a series of thresholds on a RooRealVar to
      define its state.

 o RooThreshEntry

    - Support class for RooThresholdCategory

 o RooPdfCustomizer

    - Utility class that serves a factory to build multiple PDFs from a single prototype
      that have slightly different leaf nodes.

      The class takes a proto type and a master index category in the constructor.
      A series of splitting rules determines how given leaf nodes are to be 'split'
      over the master index category or a subset of the master index (in case the master
      index is a RooSuperCategory)

      The instiated 'split' leaf nodes are put in an argset referenced in the constructor.
      and the owner of the argset is responsible for deleting them (or passing them on
      to another RooPdfCustomizer). The instantiated branch nodes are owned by the customizer.

 o RooSimFitContext

    - Specialized fit context, derived from RooFitContext, that optimizes the likelihood
      calculation in case the top level pdf is a RooSimultaneous. The original data
      set is broken into pieces, corresponding to a single state of the RooSimultaneous
      index category and those data subsets are combined with the corresponding PDF branches
      of the RooSimultaneous to form an array of regular RooFitContexts. The total likelihood
      is calculated as the sum of the likelihoods from the array of fit contexts.

      The NLL output from each subcontext is cached and only recalculated if a parameter
      that the PDF of that subcontexts depends on, is changed.

      This form of calculation is very efficient for fits where the correlation matrix has
      a block diagonal form. The CPU time in RooSimFitContext scales (approximately) with
      the number of elements in the block diagonal elements instead of with the total number
      of elements.

 o Nearly all classes

    - A large number of minor bugs has been fixed and many functions
     that are called very frequently have been inlined, made non-virtual or
     have been eliminated, following the result of repeated profiler studies.

 *** Changes to allow a dataset to cache of derived objects  ***

 o RooAbsReal, RooAbsCategory and RooAbsString

   Now each implements a protected method attachToTree, which allows to
   connect the cache of any RooAbsArg to a TTree column
   All other implementations (RooRealVar etc) removed

 o Most classes

   Type-blind assignment RooAbsArg* <...>::operator(const RooAbsArg*)
   has been replaced by RooAbsArg::copyCache(RooAbsArg *), which is
   needed for data set copy operations.

   A new method RooAbsArg::syncCache(RooDataSet *)
   can be used force to update the cache before a copyCache call.

 o RooDataSet

   - Holds a list of _cacheVars in addition to _vars, which are not
     owned by the data set, but are updated nevertheless.
     The cache list is not copied in a Clone() or copy operation.

   - New methods cacheArg(RooAbsArg&) and cacheArgs(RooArgSet&)
     register derived objects for caching in the dataset.

     The values for these derived objects for each row of the tree
     will be calculated and stored as a new column in the tree.

     The cache of the derived object is attached to that tree column.
     On a RooDataSet:get() row-load call, a setDirty(kTRUE) is called
     for each cached (and uncached) object to propagate a value change
     to the cached objects clients. Then immediately a setDirty(kFALSE)
     is performed on the cached objects, to impose that the tree-loaded
     value of the cache is correct and doesn't need to be recalculated.

 o RooFitContext

    - Optimizer not uses cacheArgs instead of addColumn, which
      is integration-safe and can now be used on any derived object
      with constant parameters


 o RooAbsPdf

    - Another iteration in the structure of getVal.
      To make data set attachement work, the normalized value is
      now stored in the cache instead of the raw value.

 *** Cleanup of assignment operator ***

 o RooAbsRealLValue/RooAbsCategoryLValue

     - Implements assignment to Double_t/(Int_t,const char*)

 o RooRealVar/RooCategory

     - Implemements assignment to RooRealVar/RooCategory

 o All other assignment operators deprecated

     - No more assignment of derived types to each other
       (conceptually unclear)

  o (Most classes)
    Merge X(const x&) and X(const char*, const X&) copy constructors
    into a single X(const& X, const char*=0)

  o RooAbsArg
    - Add 'depth-aware' client-server management functions

      recursiveRedirectServers(...)
      treeNodeServerList(...)
      leafNodeServerList(...)
      branchNodeServerList(...)
      overlaps(...)
      dependsOn(...) (now recursive)

    - Add/move parameter/dependent interpretation to RooAbsArg

      getParameters(...)
      getDependents(...)
      dependentOverlaps(...)
      checkDependents(...)

    - Change Clone() to Clone(const char*) and make it call
      a pure virtual clone().

  o RooAbsPdf

     - First implementation

     - Actual fitting implemented in RooFitContext

     - Incorporates normalization technology from
       RooNormFunction (now retired)

     - Separate getValNorm() dropped in favour of
       getVal(const RooDataSet* =0)

     - getVal(...) provides all owned proxies with
       the correct data set (which they need for their
       value cast operators that don't take an RDS)

  o RooFitContext

     - First implementation

     - Owns a clone of a dataset and a PDF and ties them
       together with a redirectServers

     - Caches indexed parameter list for fast Minuit lookup

     - global Optimizer function seeks out PDF components
       that only have constant parameters and add these
       as precalculated columns to the data set clone
       (redirectServers edits PDF tree to point to cache)

  o RooDataSet

     - Implement addColumn(RooAbsReal) that adds a column
       of precalculated values given function for each
       row of the data set

  o RooAbsReal

     - Change getVal() to getVal(const RooDataSet* set=0)
       to allow dynamic normalization for PDFs.

  o RooArgProxy and dependents

     - Cache last data set used, for use in getVal(...) call in
       value cast operator.

  o RooRealProxy

     - add min()/max() functions that get out the integration limits
       if the underlying real is a RooRealVar. (Needed by RooAbsPdf
       analytical integration implementations)

  o (Most classes)

     - A large number of minor fixes have been applied to make
       the Solaris 5.7 compiler happy

 o Implement concept of dynamic parameter/dependent distinction
   in RooNormFunction. Every function that needs this information
   has to supply a RooDataSet* to define what are the dependents

   Several changes propagate into RooRealIntegrator.

 o RooDerivedReal:

    - Extend analytical integral interface so that function can,
      given a list of reals and categories, indicate which subset it
      can analytically integrate / efficiency sum.

 o RooRealIntegral

    - Can now perform combined analytical/numerical integration.
      The RooDerivedReal is asked for the largest part it can
      analytically integrate/sum, the rest is taken care of numerically.

      The actual numerical integration algorithm is migrated into
      a dedicated class.

      RRI now also handles higher dimensional numerical integrals,
      provided there is a integrator class available for that

 o RooAbsIntegrator (new)

      Abstract base class for numerical integrators

 o RooIntegrator1D (new)

      Implementation of 1-dimensional numerical integrator that
      used to be implemented in RooRealIntegral

 o Another major round of const-correctness improvements

 o Add RooDerivedReal as an intermediates class between
   RooAbsReal and RooRealFormula,RooRealIntegral,RooUnblind*

   the getVal() -> cache check -> traceEval() -> evaluate()
   chain has been moved into this class.

   Derived Classes of RooDerivedReal only need to implement
   evaluate() for contents definition. The getVal() of RooAbsReal
   return the straight contents of _value.

 o Added RooRealIntegral class, which represents the integal and/or sum
   over various RooRealVar/RooCategory dependents of a generic RooDerivedReal

   Integral value is cached and updated when the value of one of the
   non-integrated dependents of the integrated functions changes
   (detected via valueDirty bit propagation), or if the integration ranges
   of one of the integrated dependents change (detected via shapeDirty
   bit propagation).

   If the RooDerivedReal supports analytical integration (implemented
   via the getAnalyticalIntegral/analyticalIntegral functions) it's
   analytical integrator is used. Otherwise a numerical integration algorithm
   is used (currently limited to 1-dimensional integrations)

   Summation of an arbitrary number of category dependents is supported
   but not implemented yet, pending the port of RooSuperCategory, which
   will support a trivial implementation.

   Analytical integation interface: Each RooDerivedReal has 2 functions
   implemented

      - getAnalyticalIntegral(RooArgSet& integrandList),
        which determines if analytical integration is supported
        for the given list of integrands. If not, it returns
        code 0. If yes, it returns a positive code, which RooRealIntegral
        will pass to analyticalIntegral().

      - analyticalIntegral(Int_t code) Performs or dispatches the
        analytical integral represented by the code assigned by
        getAnalyticalIntegral()

   In theory, the above scheme could be implemented with just one
   function, returning a pointer to a member function, but
   pointer-to-members are not supported by ROOT due to portability
   problems. The current scheme is inspired on the TFormula implementation
   of referencing external parameters.

   A default implementation in RooDerivedReal handles the default
   (no analytical integration available) case.
