   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)

       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  RooDataSet

     - Introduce pool-based memory allocation scheme

     - In ctor for composite datasets with Link() ensure that 
       order of observables is preserved to allow use of assignFast()
       

  o  RooRealSumPdf

     - Use getNorm() in expectedEvents() rather than createIntegral()


  o  RooAbsCollection

     - Do no allocate hash tables by default

     - Introduce contents claim counter to counter 'foreign' ownership
       claims of contents (needed for RooAbsOptTestStatistic::setData()
       support)

     - If collection is owning, only delete contents if claim count is also zero

     - In snapshot() raise hash table threshold from 100 to 1000


  o RooRefCountedList

     - Disable hash tables by default


  o RooStudyPackage

     - Make study package own clone of incoming workspace

     - Implement copy ctor


  o RooAbsTestStatistic

     - Implement 'master' setData() method. Forward to setDataSlave()
       of self for monolithic likelihoods or forward data components
       to likelihood components in case node is SimMaster. If data
       is not fast-splittable, execute slow split.


  o RooAbsData

     - Implement 'live check' to be able to conclude if a given dataset
       pointer points to a live or dead object

     - Claim contents of _vars through new claim mechanism. Release
       in dtor, allow _vars to delete contents if claim count is zero

     - Add concept of owned component datasets to support fast-splitting
       of dataset

     - Add method canSplitFast() that indicate if fast split is available
       (only possible if dataset was created as composite)

     - Add method getSimData() that retrieves pointer to component
       RooDataSet representation for a given index state


   o RooObjCacheManager

     - Add static mechanism that allows to deleted cached observables lists used for
       cache optimization triggers to be deleted on a sterilize() action. This
       is useful on toy studies with setData() operation, that would otherwise
       collect very large lists of observable clones during the toy cycle.


   o RooAbsPdf

     - Set contraint term to ADirty to avoid synchronization problems when using
       setData() in the likelihood


   o RooAbsArg

     - In clone operations set hash table threshold at 1000 nodes

     - In getObservables() use pass-by-value iterators rather than heap iterators
       to making this faster. Also make getObservables() non-virtual, as it is in
       fact not overloaded in any subclass (anymore). Also remove looping over
       branch nodes to call getObservablesHook() as no class implements method
       anymore.

   
   o RooAddition

     - Implement a setData() method that forwards to its components. Allows transparent
       operation of setData() on likelihood objects with constraint terms


   o RooLinkedList

     - Add method that returns iterator by value (simply forwards to similar implementation
       in RooLinkedList)


   o RooSimGenContext   

     - Move calculation of fraction table from ctor to dedicated updateFraction() method

     - Before each generation sequence call updateFractions() so that multi-generation
       sequence are robust against parameter changes between calls

     - In createDataSet() always make a composite dataset if the index is present, as this
       allows faster use in toymc operations


   o RooAbsOptTestStatistic

     - Initialize all variables in default ctor

     - In dtor and ctor handle ownership of dataset observables, on which we put a claim
       (i.e. we need to delete contents if the test statistics survives the dataset)

     - Reimplement existing setData() as setDataSlave(), and add claim management on
       dataset observables. When attached new data to function, request that object caches
       clear full content in sterilize() operation to avoid buildup of cache objects in
       long toy runs.

     - In setData() adjust event count of test statistics, for correct functioning of extended
       terms after update


   o RooArgSet

      - In ctor for list and a single object, only add object if not already in list
        (is already checked, but new procedure preserves order of list elements in case
         object was already present)

   o LinkDef

      - Add list<RooAbsData*> and map<string,RooAbsData*> to support streaming of composite datasets


   o RooAbsStudy

      - Implement clone method to support polymorphic array cloning

 
   o RooAbsReal

      - Add interface method setData() 


   o RooProfileLL

      - When storing coordinates of absolute minimum, store only those that are non-constant.
        Otherwise option to restart each minimization from known absmin may alter constant
        parameters

   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
      caching RooDataHist not to forward dirty state propagation calls
      and set sampling pdf clones to AlwaysDirty to increased operational
      efficiency.


 o RooChangeTracker

   - Add parameters() method returning the tracked parameters


 o RooRealSumPdf

   - Implement component selection functionality in plotting as
     is available for RooAddPdf


 o RooEfficiency

   - Implement analytical integral over acceptance category
     (it is always 1.0)


 o RooHist

   - Implement ability to handle RooAbsData::None error bars
     (i.e no errors)

   - Expand functionality of constructor taking two TH1s
     to also represent the efficiency binomial in addition
     to the assymmetry binomial

   - Add addEfficiencyBin() method to handle calculation
     of efficiency bins.


 o RooAbsReal

   - Make named argument version of fitTo() default method
     when invoked with no arguments

   - In fitTo(), if pdf is extendable and no explicit Extended() argument
     is given, automatically included extended likelihood term

   - In fitTo(), disable default running of MINOS when invoked without
     arguments

   - Move component selection functionality from RooAbsPdf
     to here so that it also works for RooRealSumPdf, which
     takes RooAbsReals as components rather than RooAbsPdf

   - Add simplified createHistogram() method that takes
     string with comma separated observable names and
     three optional bin numbers. 

   - Add createHistogram() method that takes a list of
     RooCmdArgs that can serve as backend for all user
     interface methods.

   - In plotOn() support the new Slice() argument for categories
     that allow inline specification of of the slice position.

   - Also add support for the PrintEvalErrors(Int_t numErr) and
     EvalErrorValue(Double_t value) arguments to allow better control
     of evaluation error handlign during plotting.

   - Also add support for the MoveToBack() argument that immediately
     inserts the curve at the bottom of a RooPlot stack.


 o RooProduct 
   
   - Remove erroneous assert()


 o RooAbsCollection

   - In snapshot(), only add "Snaphot of" to name if original
     has a non-null name.

   - In verbose printing mode, remove printing of 'extras' and
     only print '(owning contents)' of collection has a non-null name


 o RooAddPdf

   - Fix logic of recursive fractions constructor. Recursive additions
     happen start on the rightmost pair of pdfs, recursively adding
     one more pdf to the left at each iteration. Coefficients describe
     the fractions of the leftmost pdf in each recursive addition,
     starting with the outermost addition of the 1st pdf to the
     som of all other pdfs, continuing with the fraction of the
     2nd pdf being added to the sum of pdf 3-n etc...
   

 o RooAbsCachedPdf

   - Degrade 'parameters have changed' message from INFO to DEBUG

   - Interface cache histogram objects to RooExpensiveObjectCache
     with associated parameters given by RooChangeTracker

   - Fix bug in printing: only print normalization object of
     cache if it actually exists


 o RooAbsTestStatistic

   - Reimplement copy constructor to initialize from scratch from
     original contents, to support sane implemlementation of
     copying of optimized test statistics with multi-process
     calculations.
      
   - Fix redirectServers method for objects implementing multi-process
     test statistics
   
 
 o RooRecursiveFraction

   - Invert incoming list of plain fractions when filling internal
     list in ctor so that last fraction is 'special' instead of first
     to support improved handling of recursive fractions in RooAddPdf


 o RooAbsData

   - 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.
     If the bin counts are positive, the ranges of the observables
     are used for the histogram, unless the observable has an
     open-ended ranges, in which case the automatic calculation
     is used.

   - Add createHistogram() method that takes a list of
     RooCmdArgs that can serve as backend for all user
     interface methods.

   - Extend createHistogram() method with named arguments
     to take AutoBinning and AutoSymBinning arguments to
     automatically calculate the ranges of the output histogram
     with the specified number of bins.


   - Add a table() method that takes a set of RooCategories
     and returns a table of the output states of a RooSuperCategory
     of the given input categories.

   - Add support for EvalErrorWall() named argument in fitTo
     to give user control of the 'NLL wall' feature used to
     force MINUIT to retreat from regions with evaluation errors

   - Enlarge default size of box created by paramOn()

 
 o RooAbsArg

   - Add pointer to expensive object cache to use for any expensive
     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

   - In constant term optimization, prevent addition of 
     observables with parameterized ranges to cache.

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

   - Add flipAClean() accessor method for corresponding
     static data member to solve windows linkage problems.


 o RooRealIntegral

   - Add support for cache values of >1D integrals in 
     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()

 o RooMinuit

   - Deprecate support for error handling mechanisms that are now
     phase out.

   - Implement option to ignore evaluation errors   

   - Improve the contour() method to return a RooPlot containing
     contour TGraphs, rather than drawing them directory on a canvas


 o RooDouble

   - Set name to string representation of value


 o RooGlobalFunc

   - Add various named argument constructors needed by other code


 o RooCintUtils

   - New name space with CINT interaction utilities

   - Add function to match a given functin pointer to a string with
     a function argument list specification to facilitate manual overloading

==== 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

     - 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

       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.

       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()

     - 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 RooProjectedPdf

     - Fix important bug: normalization set should always include integration set for each configuration


   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

     - Implement name() function for more useful error messaging in integration


   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.

     - Add optional addContents flag to print()


   o RooArgProxy, RooSetProxy, RooListProxy

     - Implement addContents flag in print()


   o RooAbsReal

     - Reimplement stack of logged error messages in terms of custom EvalError class. 
       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()

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


   o RooNLLVar

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

       and negative values and including details in the error message

     - Add PrintEvalError(Int_t nErr) option to fitTo() to control new eval error
       message control system

     - Int printValue show both value (raw from evaluate()) as well as most recently
       used normalization value (if available)

   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

    o RooAbsData

      - Introduce reduce() version with named arguments.

      - Supports reduced in number of variables with SelectVars()

      - Supports selection of events through cut expression or RooFormulaVar with Cut()

      - Supports selection of events through pre-defined cut ranges with CutRange() [NEW]

      - Support selection of range of events by sequential number with EventRange() [NEW]


    o RooAbsGoodnessOfFit

      - Add support for fitting subsets of data/pdf combinations selected through predefined cut ranges


    o RooAbsOptGoodnessofFit

      - Implement fitting of data/PDF in a subrange as indicated by named ranges in RooRealVar.
        Automatically select only those data points that are in the indicated range and adjust
        the normalization range of the PDF variables to the selected range for the duration of
        the fit. Automatically adjust RooAddPdf fraction parameters so that RooAddPdf shapes
        are invariant under the normalization range change

  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.

    - 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
