Timing information for training and evaluation of MVA methods.
Usage:
Remark: in batch mode, the progress bar is quite ugly; you may want to use the text output then
Note that by default in TMVA::Config the drawing of the progress bar is switched off. To have the progress bar visible you need to enable it by calling TMVA::gConfig().SetDrawProgressBar(true)

#include <TMVA/Timer.h>
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.
