that '^@' or '^A' were printed out. To bypass that and properly output
"kTRUE" or "kFALSE" a new protected static function:
  const char* TEveElement::ToString(Bool_t b)
has been introduced.

This is then used wherever appropriate.

  When checking and executing a macro strip off also the directory.

* TEveManager
  InsertVizDBEntry() - rewrite logic for un-registration of clients
  from the old model.
  Also propagate changes to projected replicas if update is requested.

  LoadVizDB() - call Redraw3D() at the end.

  SaveVizDB() - expand pathname before opening the file.   

* TEveElement
  SetVizModel() - decrease fParentIgnoreCnt *before* removing itself
  from the old model and increase it *after* adding itself to the new model.

* TEveStraightLineSet
  In CopyVizParams() write out "kTRUE"/"kFALSE" for boll values.

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

fixes a major leak when merging files with collections written using kSingleKey option. In the analysis framework we use this option to be able to recreate the output content of an analysis task on the client side.

The merger was reading each key in memory and deleted the object at the end, but the container is not owner by default, so all objects inside leaked.

The value of teh function is saved at the center of the histogram bins instead of equidistant points. This makes drastic improvements when rendering the function in case of variable
bin size histograms.
