// Steering class for particle (gamma, hadron) identification and correlation 
// analysis. It is called by the task class AliAnalysisTaskCaloTrackCorrelation 
// 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 AliAnaCaloTrackCorrBaseClass
