from Axel:
Change the signature of SavePrimitive from
void SavePrimitive(ofstream &out, Option_t *option);
to
void SavePrimitive(ostream &out, Option_t *option = "");
With this change one can do, eg
myhist.SavePrimitive(std::cout);
WARNING: do rm -f tree/src/*.o

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."

Add a new function
Option_t *TMultiGraph::GetGraphDrawOption(const TGraph *gr) const
// Return the draw option for the TGraph gr in this TMultiGraph
// The return option is the one specified when calling TMultiGraph::Add(gr,option).

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.

Implement function TMultiGraph::RecursiveRemove.
When a TGraph is deleted (eg via the context menu), its parent TMultigraph
is notified to remove the TGrapg from its list of graphs.
Destructor protected.

Add an optional argument to TMultiGraph::Draw.
This optional argument can be used to specify the draw option for this graph.
If a draw option is not specified, the option specified in TMultiGraph::Draw
will be used instead.
Also, always use the option "0" when painting the frame histogram.
The option "0" suppresses the drawing of the horizonthal line at y=0.

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.

Add new class TMultiGraph.
// A TMultiGraph is a collection of TGraph (or derived) objects
// Use TMultiGraph::Add to add a new graph to the list.
// The TMultiGraph owns the objects in the list.
// Drawing options are the same as for TGraph
// Example;
// TGraph *gr1 = new TGraph(...
// TGraphErrors *gr2 = new TGraphErrors(...
// TMultiGraph *mg = new TMultiGraph();
// mg->Add(gr1);
// mg->Add(gr2);
// mg->Draw("alp");
