// -*- C++ -*-

// Package:    EgammaHLTOffline
// Class:      EgammaHLTOffline
// 
/*
 Description: This is a DQM source meant to plot high-level HLT trigger 
 quantities as stored in the HLT results object TriggerResults for the Egamma triggers

 Notes:
  Currently I would like to plot simple histograms of three seperate types of variables
  1) global event quantities: eg nr of electrons
  2) di-object quanities: transverse mass, di-electron mass
  3) single object kinematic and id variables: eg et,eta,isolation
