// PFIsolationEstimator
//
// Helper Class for calculating PFIsolation for Photons & Electron onthe fly. This class takes
// PF Particle collection and the reconstructed vertex collection as input.
//
// Authors: Vasundhara Chetluru
//--------------------------------------------------------------------------------------------------
/// --> NOTE if you want to use this class as standalone without the CMSSW part
/// you need to uncomment the below line and compile normally with scramv1 b
/// Then you need just to load it in your root macro the lib with the correct path, eg:
/// gSystem->Load("/data/benedet/CMSSW_5_2_2/lib/slc5_amd64_gcc462/pluginEGammaEGammaAnalysisTools.so");
