// Class for reading data (ESDs) in order to do prompt gamma
// or other particle identification and correlations
//
-// It is a filtering class, transforms ESD tracks or CaloClusters
-// into AOD tracks and calocluters, which are the basic input of the analysis
-// classes in this frame.
-// It is recommended to use the official filter AliAnalysisTaskESDfilter, and
-// then the reader for AODs AliCaloTrackAODReader.
