Detailed Description

This histogram class can be used to evaluate the resolution of a variable. It has a TProfile, a TH2F and a TH1F. The TProfile is used to compute the rms of the distribution which is filled in the TH1F (the resolution histogram) in the Write method. If a TDirectory is passed to the constructor, the different histograms are placed in subdirectories.
