Detailed Description

Class DHF Histogram Manager.

The class DHF implements the histogram manager. In the method BookHistos() the user can define a set histograms he want to fill at each cut level.

The method Define( ) provides a way to book automatically a many of histograms versions of the same histograms corresponding to the different event classes defined in the Class Categories these histograms are putted in a subdirectory

In the method FillAll(), the user is expected to define the rules to fill the histograms. The method FillSet() is provided to fill automagically the histos booked with the method Define().
