- Fix https://savannah.cern.ch/bugs/?30595 . The loop on the ComputeRange
methods (called for each graph in the multigraph) returned the last values
provided by the last call to ComputeRange instead of computing the minimum
and maximum of all of them. Revision 20335 introduced this bug.

Change TGraph::ComputeRange to compute the x/y range of the graph.
Move code previously in TGraph::PaintGraph or TGraph::PaintGrapHist to TGraph::ComputeGraph.
The functions like TGraphErrors::ComputeGraph call first TGraph::ComputeRange.

- The SavePrimitive mechanism did not work properly. In particular
it was not possible to save various kind of graphs in several multigraph
in the same macro. Also in case of TGraph the generated macro was wrong
(Add() was missing).

- New method: Add(TMultiGraph *multigraph, Option_t *chopt="");
it allows to add all the graphs in "*multigraph" in the current MultiGraph.
Example:
{
float x1[] = {1,2,3}; float y1[] = {4,7,6};
float x2[] = {3,5,6}; float y2[] = {0,9,4};
float x3[] = {7,8,9}; float y3[] = {1,2,4};
float x4[] = {0,6,5}; float y4[] = {5,2,7};
TGraph *gr1 = new TGraph(3,x1,y1);
TGraph *gr2 = new TGraph(3,x2,y2);
TGraph *gr3 = new TGraph(3,x3,y3);
TGraph *gr4 = new TGraph(3,x4,y4);
TMultiGraph *mg1 = new TMultiGraph();
mg1->Add(gr1); mg1->Add(gr2);
TMultiGraph *mg2 = new TMultiGraph();
mg2->Add(gr3); mg2->Add(gr4);
mg2->Add(mg1); // mg2 now contains gr1 gr2 gr3 and gr4
mg2->Draw("AL*");
}

From Anna:
- TFormula::EvalPar() is not changing parameters (the fParams data member) when a user passes his own uparams array as a second argument. Before - sometimes it did, sometimes it didn't.
- TF1::GradientPar() is now 0 on fixed parameters
- TFitter::GetConfidenceIntervals() is now taking the fixed parameters into account
- TLinearFitter::GetConfidenceIntervals() is now taking the fixed parameters into account
- TLinearFitter::FixParameter() can now be called before a first fit is performed (an accidently found bug :))
- TLinearFitter::Eval() now returns 1 if there are errors in the fit. According changes in:
--TH1
--TGraph
--TGraph2D
--TMultiGraph

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."

Reduce direct dependencies on TClass.h, TROOT.h and TStreamerInfo.h.
Warning: This means that some file that relied on the indirect
inclusion of these header file might now fail to compile with
an error message mention that gROOT is no known or that TClass,
TROOT or TStreamerInfo is incompletely defined. Simply add the
proper include directive.

From Anna Kreshuk:
Methods to compute Least trimmed squares regression coefficients
were added to the TLinearFitter class.
Now robust linear fitting can be performed for the datasets, in which
outliers influence the ordinary least-squares fit. The maximal breakdown
point of the algorithm is |(floor((n-p)/2) +1)/n, which means that
LTS fit stays in a bounded region whenever floor((n-p)/2) or fewer
observations are replaced by arbitary points.
The implementation is based on the article "Computing LTS regression
for Large Data Sets" by Peter J. Rousseeuw and Katrien Van Driessen.

is not needed anymore in all the .cxx's files using Foption_t. This was
error prone as two new Foption_t members were not initialized in some

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 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.
