From Anna:
Implement new functions in the TVirtualFitter and corresponding
implementations to compute the confidence intervals.
Two kinds of interfaces are implemented, eg
void TFitter::GetConfidenceIntervals(Int_t n, Int_t ndim, Double_t *x, Double_t *ci, Double_t cl)
//Computes point-by-point confidence intervals for the fitted function
//Parameters:
//n - number of points
//ndim - dimensions of points
//x - points, at which to compute the intervals, for ndim > 1
// should be in order: (x0,y0, x1, y1, ... xn, yn)
//ci - computed intervals are returned in this array
//cl - confidence level, default=0.95
//NOTE, that the intervals are approximate for nonlinear(in parameters) models
void TFitter::GetConfidenceIntervals(TObject *obj, Double_t cl)
//Computes confidence intervals at level cl. Default is 0.95
//The TObject parameter can be a TGraphErrors, a TGraph2DErrors or a TH1,2,3.
//For Graphs, confidence intervals are computed for each point,
//the value of the graph at that point is set to the function value at that
//point, and the graph y-errors (or z-errors) are set to the value of
//the confidence interval at that point.
//For Histograms, confidence intervals are computed for each bin center
//The bin content of this bin is then set to the function value at the bin
//center, and the bin error is set to the confidence interval value.
//NOTE: confidence intervals are approximate for nonlinear models!
//
//Allowed combinations:
//Fitted object Passed object
//TGraph TGraphErrors, TH1
//TGraphErrors, AsymmErrors TGraphErrors, TH1
//TH1 TGraphErrors, TH1
//TGraph2D TGraph2DErrors, TH2
//TGraph2DErrors TGraph2DErrors, TH2
//TH2 TGraph2DErrors, TH2
//TH3 TH3

Implement a cache facility in TVirtualFitter.
The class has a new function TVirtualFitter::SetCache that creates
an internal structure where the information about histogram bins
is stored (bin position, size, content and error).
The cache is used during fitting and speeds up (factor 2) TH1::Fit
when called with the default TMinuit. Only the points included in
the fit are stored in the cache.
Currently the cache is set and filled only in TH1::Fit.
The TFitter and TFumili classes have been changed to take into account
the information in the cache.
The free functions called by Minuit have been rewritten.
They are now only an interface calling the fitter member functions.

In TVirtualFitter, TFitter and TFumili, rename the recently introduced
function GetNpar to GetNumberTotalParameters to avoid a possible confusion
with the member fNpar in TMinuit that contains the number of free parameters.

In TVirtualFitter make the following functions const
Double_t Chisquare(Int_t npar, Double_t *params) const = 0;
Double_t *GetCovarianceMatrix() const = 0;
Int_t GetErrors(Int_t ipar,Double_t &eplus, Double_t &eminus, Double_t &eparab, Double_t &globcc) const = 0;
Int_t GetParameter(Int_t ipar,char *name,Double_t &value,Double_t &verr,Double_t &vlow, Double_t &vhigh) const = 0;
Int_t GetStats(Double_t &amin, Double_t &edm, Double_t &errdef, Int_t &nvpar, Int_t &nparx) const = 0;
Add a new function
Double_t GetCovarianceMatrixElement(Int_t i, Int_t j) const;
Similar changes in TFitter and TFumili.

Many changes in the class to accomodate the changes in TVirtualFitter.
The objective functions H1FitChisquare and H1FitLikelihood previously in TH1
or TGraph have been moved to TFitter.
The global variables communicating with TH1 or TGraph have been replaced
by the functions in TVirtualFitter.

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.
