// Steering class for particle (gamma, hadron) identification and correlation analysis
// It is called by the task class AliAnalysisTaskParticleCorrelation and it connects the input 
// (ESD/AOD/MonteCarlo) got with AliCaloTrackReader (produces TClonesArrays of AODs 
// (TParticles in MC case if requested)), with the 
// analysis classes that derive from AliAnaPartCorrBaseClass
