Data Members

    private:

                     Int_t fNcounts          reference number of "counts" 
                   TString fPrefix           prefix for outputs
                    Bool_t fColourfulOutput  flag for use of colors
      static const TString fgClassName       used for output
        static const Int_t fgNbins           number of bins in progress bar

 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 !)
      cout << " time left: " << timer.GetLeftTime( i ) << endl;

    }
    cout << "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

 constructor

 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.

 destructor

 timer initialisation

 resets timer

 computes elapsed tim in seconds

 returns pretty string with elaplsed time

 returns pretty string with time left

 draws progress bar in color or B&W
 caution:

 pretty string output
