Class Description

                                                                      
 Timing information for training and evaluation of MVA methods  
 
 Usage:

    TMVA::Timer timer( Nloops, "MyClassName" ); 
    for (Int_t i=0; i<Nloops; i++) {
      ... // some code

      // now, print progress bar:
      timer.DrawProgressBar( i );

      // **OR** text output of left time (never both !)
      fLogger << " time left: " << timer.GetLeftTime( i ) << Endl;

    } 
    fLogger << "MyClassName" << ": elapsed time: " << timer.GetElapsedTime() 
            << Endl;    

 Remark: in batch mode, the progress bar is quite ugly; you may 
         want to use the text output then
_______________________________________________________________________
Timer( Bool_t colourfulOutput )
 constructor
Timer( Int_t ncounts, TString prefix, Bool_t colourfulOutput )
 standard constructor: ncounts gives the total number of counts that 
 the loop will iterate through. At each call of the timer, the current
 number of counts is provided by the user, so that the timer can obtain
 the due time from linearly interpolating the spent time.
~Timer( void )
 destructor
void Init( Int_t ncounts )
 timer initialisation
void Reset( void )
 resets timer
Double_t ElapsedSeconds( void )
 computes elapsed tim in seconds
TString GetElapsedTime( Bool_t Scientific )
 returns pretty string with elaplsed time
TString GetLeftTime( Int_t icounts )
 returns pretty string with time left
void DrawProgressBar( Int_t icounts )
 draws progress bar in color or B&W
 caution:
TString SecToText( Double_t seconds, Bool_t Scientific )
 pretty string output
Timer( Bool_t colourfulOutput = kTRUE )
