// Package:    ZDCDigiStudy
// Class:      ZDCDigiStudy
//
/*
  Description:
  This code has been developed to be a check for the ZDC sim. In 2009, it was found that the ZDC Simulation was unrealistic and needed repair. The aim of this code is to show the user the input and output of a ZDC MinBias simulation.
 
  Implementation:
  First a MinBias simulation should be run, it could be pythia,hijin,or hydjet. This will output a .root file which should have information about recoGenParticles, hcalunsuppresseddigis. Use this .root file as the input into the cfg.py which is found in the main directory of this package. This output will be another .root file which is meant to be viewed in a TBrowser
