- remove assert in TFitResultPtr and print instead an error messages
- implement TFitRresult::Print and method to retrieve a covariance and correlation matrix as a TMatrixDSym
FitResult:
- fix a bug in FitResult in returning the correlation matrix for fixed parameters
- improve printout in case of empty classes

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

Implemented the new TFitResult class. This is an indirection to
ROOT::Fit::FitResult that inherits from TObject, making it possible to
be stored and read from a TFile.
Also remove the methods DoFit from TH1, TGraph, TMultiGraph and
TGraph2D, that were making an unnecessary indirection.
All the fit methods of the mentioned classes now return a TFitObject
class so that the users can inspect it. This implements a conversor to
int, so that the client's code doesn't need to be changed to continue
working.
The TFitResult will not be filled with a FitResult object unless
option "S" is especified in the Fit method.
