// Example class on how to read AODCaloClusters, ESDCaloCells and AODTracks and how 
// fill AODs with PWG4PartCorr analysis frame
// Select the type of detector information that you want to analyze, CTS (tracking), PHOS or EMCAL
// Select the PID custer type of the calorimeters
// Set min momentum of the cluster/tracks
// Fill few histograms
