/**
@class ZAnalysis.h
@brief Class to analyse events of the type QCD pp->Z->ee, Z->mumu Processes.
       Examples to generate these events are given in the specific generator
       directory, e.g. examples/pythia6 ; the histogramm output is stored
       in the Zanalysis folder of the root file.
