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.

merge from https://root.cern.ch/svn/root/branches/dev/mathDev/hist/hist up to revision 31170
from David and myself
Summary of major changes:
- TFitResult, TFitResultPtr
- add new class TFitResult which extend FitResult with TNamed for the I/O. The result of the fit , including covariance and correlation matrix, minos errors, etc... can then be stored in a file
- add a class TFitResultPtr which behaves like a pointer to TFitResult and can be converted to an integer. This class is now returned by TH1::Fit and TGraph::Fit. By default the class contains only the returned integer status of the fit. If option "S" is used the class contains a pointer to TFitResult which can be retrieved using the -> or * operators (like a smart pointer)
The conversion to int provides backward compatibility with the old signature ( int TH1::Fit )
- TH1, TGraph, TGraph2D, TMultiGraph
change from int Fit(....) to TFitResultPtr Fit(.....)
remove internal function DoFit
- THnSparse
add functionality for fitting a sparse histogram. Default method is the likelihood one. Chi2 can be used with the new option "X"
- FOption
- add some new options for fitting:
"S" for storing the fit resul
"X" for forcing chi2 fit in case of THnSParse
"EX0" for neglecting errors in X when fitting TGraphErrors
- WrappedMultiTF1
- make the wrapper for TF1 multi-dim function implementing the gradient interface
Minos changes:
TH1:
- add check of compatibility for each bins when using Add on variable bin histograms
TH3:
- fix a bug in setting the entries for a projected 2d profile when using weights
THNSParse:
- set also the entries (and reset statistics) in the projected sparse histogram
TFormula:
- define the number for the 2d function like xygaus or xylandau
HFItInterface:
improve filling data for histograms (add support for bin volume normalization)
add initialization for exponential and 2d gaus functions

Implement a new function computing the integral of a graph
Double_t TGraph::Integral(Int_t first, Int_t last) const
{
// Integrate the TGraph data within a given (index) range
// NB: if first=last=0 (default) take the full range from 0 to fNpoints-1
// if (first >= last) the function returns 0.
// : The graph segments should not intersect.
//Method:
// There are many ways to calculate the surface of a polygon. It all depends on what kind of data
// you have to deal with. The most evident solution would be to divide the polygon in triangles and
// calculate the surface of them. But this can quickly become complicated as you will have to test
// every segment of every triangle and check if they are intersecting with a current polygon?s
// segment or if it goes outside the polygone. Many calculations that would lead to many problems...
// The solution
// Fortunately for us, there is a simple way to solve this problem, as long as the polygon?s
// segments don?t intersect.
// It takes the x coordinate of the current vertex and multiply it by the y coordinate of the next
// vertex. Then it subtracts from it the result of the y coordinate of the current vertex multiplied
// by the x coordinate of the next vertex. Then divide the result by 2 to get the surface/area.

Import changes from math development branch, in particular a re-implementation of
fitting methods for the histogram and graph objects.
NOTE: Since some files are removed, a make clean-hist is needed in order to be able
to compile hist after an svn update.
The implementation of TH1::Fit, TGraph::Fit, TGraph2D::Fit and TMultiGraph::Fit is
done in a common function implemented in HFitImpl.cxx (HFit::Fit).
In addition the file HFitInterface.h define ROOT::Fit::FitObject functions passing
option directly via Foption class and not by a string. They are used by the FitPanel.
Remove previously existing files THistFitInterface.cxx (and *.h) and
TGraphFitInterface.cxx (and *.h). The code is now in the HFitInterface.cxx (and *.h)
files.
Use plugin manager directly to open the Fit Panel. Do not pass anymore via the THistPainter.
Changes in TH1::FitPanel, TGraph::FitPanel.
Add FitPanel() method for TGraph2D and TMultiGraph.
Add new class TBackCompFitter, providing a backward compatible implementation of
TVirtualFitter using the new fitting class. It is constructed from the fitter class
and can be used to retrieve the fit information (result and configuration) via the
TVirtualFitter API from FitConfig and FitResult. A static istance is created after
calling the Fit method.
Other changes are:
TGraph:
- when creating a graph from an histogram, don't use the same name.
Otherwise it will conflict later with histogram created internally by the TGraph.
TH2:
add protected method TH2::DoFitSlices and TH2::DoProfile as common implementations
for (FitSlicesX,FitSclicesY) and (ProfileX, ProfileY).
pass the global statistics in DoProjection when range is (1,NBIN)
TBinimialEfficiencyFit:
add possibility to set verbose option, and set different precision and
max iterations for minimizing.

From Olivier and me:
Split the TGraph classes to move the graphics code to separate classes.
These classes will be moved to the hist directory once the classes will be ok.
The TGraphs are painted via the TVirtualGraphPainter class and its concrete
implementation TGraphPainter.
At the difference of the TH1 classes for which a different painter is created
when drawing each histogram, one single TGraphPainter class is created.
The TGraphPainter class does not have internal state, all the information
from TGraph is passed to the drawing functions via parameters.

{
// Return the chisquare of this graph with respect to f1.
// The chisquare is computed as the sum of the quantity below at each point:

// ey**2 + (0.5*(exl + exh)*f1'(x))**2
//
// where x and y are the graph point coordinates and f1'(x) is the derivative of function f1(x).
// This method to approximate the uncertainty in y because of the errors in x, is called

From Federico Carminati:
"I have implemented all copy and equal operators needed to silence all
warnings in AliRoot, as requested. I have implemented shallow copies as
would do the default operators synthetized by the compiler.
Most operators are protected. If users complain, you just have to move
them into the public area, but class derivation is of course supported.
It has been a terrible job, I have modified 278 files, but the changes
are backward compabile, and this goes a long way to permitting user to
use the effc++ flag with root headers."

- When a graph is painted with the option "C" or "L" it is now possible to draw
a filled area on one side of the line. This is useful to show exclusion
zones. This drawing mode is activated when the absolute value of the
graph line width (set thanks to SetLineWidth) is greater than 99. In that
case the line width number is interpreted as 100*ff+ll = ffll . The two
digits number "ll" represent the normal line width whereas "ff" is the
filled area width. The sign of "ffll" allows to flip the filled area
from one side of the line to the other. The current fill area attributes
are used to draw the hatched zone.
This new functionality is implemented thanks to the new method
PaintPolylineHatches().

From Marek:
- TH1::Merge() adding overflows even when merging histograms with the
same limits. If the limits are different the overflows are ignored.
The same in TH2::Merge, TH3::Merge, TProfile::Merge and TProfile2D::Merge.
- Cleaning fHistogram (and this kind of) variables, so that the drawn
plots aren't deleted in the TProofDrawXXX's destructor.
- Removed TProofNTuple from TProofDrawTGraph.
- Put the initialization code of fFeedback and fPlayer (=MakePlayer())
in TProof in to Init().
- Added TGraph::Merge(). Added TPolyMarker3D::GetPoint(Int_t, Float&,
Float&, Float&).
- Removed TProofNTuple from TProofDrawPolyMarker3D.
- Fixed cleaning output lists after processing (set option = "nodelete").
Now the objects are on the player outputlist and are removed (but not
deleted) from the selector's outputlist.
- Fixed TPolyMarker3D::Merge() - it seems that nobody has ever tried to
run this function.
- Added setting tree attributes (like MarkerStyle, MarkerSize, LineColor etc.)
to a drawn TGraph and TPolyMarker3D in TProofDrawGraph and
TProofDrawPolyMarker3D.

From Anna Kreshuk:
- TLinearFitter class: Linear fitter is used to fit a set of data points with a linear
combination of specified functions (with or without weights). The "linear" in the name
stands for "linear in parameters", not variables. The main advantages,
compared to a general non-linear fitter, is that the linear fitter is considerably
faster and doesn't require setting the initial values of parameters.
The linear fitter can be used directly or through TH1::Fit and TGraph::Fit functions
When it's used directly, functions of more than 3 dimensions can be fitted.
- TFormula: a new data member fLinearParts and methods to process it are added. Now
one can create a function of the type that can be fit by the linear fitter.
Example: TFormula f("f", "x++sin(x)") is equivalent to
TFormula f("f","[0]*x + [1]*sin(x)"), but if a TH1::Fit or a TGraph::Fit is performed
with the 1st formula, it goes through the linear fitter, if it's performed with the
2nd formula, it goes through Minuit.
- TMultiGraph class: the Fit method is implemented, allowing to fit all the graphs
of a multigraph simultaneously
- TGraph, TGraphErrors, TGraphAsymmErrors, TGraphBentErrors - functions GetEXhigh(),
GetEXlow(), GetEYhigh(), GetEYlow() implemented to simplify the GraphFitChisquare()
function of the TFitter class
- TH1, TGraph, TGraph2D, TMultiGraph - changes in the Fit functions, allowing to use
the linear fitter. Fitting with "polN" functions redirected to use the linear fitter,
in cases where no options, except "range", are specified.

Add two optional arguments in TGraph::Fit Axis_t xmin,Axis_t xmax (like in TH1::Fit).
These two arguments can be given to select a fit range.
// Fit range
// =========
// The fit range can be specified in two ways:
// - specify rxmax > rxmin (default is rxmin=rxmax=0)
// - specify the option "R". In this case, the function will be taken
// instead of the full graph range.

Add new functions to all the TGraph classes to interactively with the mouse
add a new point or remove a point. These new functions are available
from the context menu.
Int_t InsertPoint();
Int_t RemovePoint();
Add new function SetPointError in TGraphErrors and TGraphAsymmErrors.
This new function is also in the context menu.

Add two new TGraph constructors accepting TVector, TVectorD as input:
TGraph(const TVector &vx, const TVector &vy);
TGraph(const TVectorD &vx, const TVectorD &vy);
The number of points in the graph is the minimum of vx and vy.

In all the TGraphX classes add a new method Apply suggested and implemented by
Miroslav Helbich <helbich@mail.desy.de>
If one has points x,y of TGraph, sometimes it is convenient to apply a
function to those points e.g y=f(x,y). There are few examples I've been
dealing with, like scale the points by some number f(x,y)=y*scale factor
or if you try to fit some complicated formula it is sometimes better to do
the transformation first.
For classes TGraphErrors and TGraphAssymErrors the situation becomes a
little bit more complicated since the error bars have to be changed.

W A R N I N G !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
==================================================================
A very long list of changes in this pre-release of version 3.00.
We have modified the signature of many functions (in particular TObject)
to introduce more constness in the system.
You must change your code if your class derives from TObject and uses
one of the modified functions such as ls, Print, Compare, Hash, etc.
The modified functions in TObject have the following signature:
virtual TObject *Clone() const;
virtual Int_t Compare(const TObject *obj) const;
virtual void Delete(Option_t *option=""); // *MENU*
virtual void DrawClass() const; // *MENU*
virtual void DrawClone(Option_t *option="") const; // *MENU*
virtual void Dump() const; // *MENU*
virtual TObject *FindObject(const TObject *obj) const;
virtual char *GetObjectInfo(Int_t px, Int_t py) const;
virtual ULong_t Hash() const;
virtual void Inspect() const; // *MENU*
virtual Bool_t IsEqual(const TObject *obj) const;
virtual void ls(Option_t *option="") const;
virtual void Print(Option_t *option="") const;
A similar operation has been done with classes such as TH1, TVirtualPad,
TTree, etc.

The internal dynamic arrays fX and fY have their type changed from Float_t to Double_t
The members fMaximum, fMinimum changed from Float_t to Double_t
class VersionID changed from 1 to 2.
New constructor:
TGraph(Int_t n);
The arguments of the other constructors are now mandatory:
TGraph(Int_t n, Float_t *x, Float_t *y);
TGraph(Int_t n, Double_t *x, Double_t *y);
The following functions have their arguments or return type
changed from Float_t to Double_t:
virtual void ComputeRange(Double_t &xmin, Double_t &ymin, Double_t &xmax, Double_t &ymax);
virtual void DrawGraph(Int_t n, Double_t *x, Double_t *y, Option_t *option="");
virtual Double_t GetErrorX(Int_t bin);
virtual Double_t GetErrorY(Int_t bin);
Double_t *GetX() {return fX;}
Double_t *GetY() {return fY;}
virtual void GetPoint(Int_t i, Double_t &x, Double_t &y);
virtual void PaintGraph(Int_t npoints, Double_t *x, Double_t *y, Option_t *option="");
virtual void PaintGrapHist(Int_t npoints, Double_t *x, Double_t *y, Option_t *option="");
virtual void SetMaximum(Double_t maximum=-1111); // *MENU*
virtual void SetMinimum(Double_t minimum=-1111); // *MENU*
void Smooth(Int_t npoints, Double_t *x, Double_t *y, Int_t drawtype);
void Zero(Int_t &k,Double_t AZ,Double_t BZ,Double_t E2,Double_t &X,Double_t &Y
,Int_t maxiterations);
- Mods in TGraph.cxx. See changes in TGraph.h.
TGraph::Streamer modified to read old objects written in single precision.
