-// AliAnalysisTaskCheckPerformanceCascadePbPb class
-// This task is for a performance study of cascade identification in PbPb.
-// It works with MC info and ESD/AOD.
-// Origin : AliAnalysisTaskCheckPerformanceCascade class by A. Maire Nov2010, antonin.maire@ires.in2p3.fr
-// Modified for PbPb analysis: M. Nicassio Feb2011, maria.nicassio@ba.infn.it:
-// - physics selection moved to the run.C macro
-// - added centrality selection and possibility to select events in nTracks ranges
-// - added new histograms
-// - modified binning of some histograms and containers
-// - flag to enable CF container usage
-// - check in the destructor for CAF usage
-// - flag for acceptance cut in the MC part
-// - in the MC particle selection IsPhysicalPrimary added and number of particles taken as appropriate for HIJING
-// (however for cascades one gets the same if runs on Nprimaries in the stack and does not check IsPhysicalPrimary)
-// - automatic settings for PID
-// - selection of injected cascades and HIJING cascades (kind of "bug" in method IsFromBGEvent())
-// - added proper time histograms for cascades and lambdas
-// - cos of PA V0 wrt Xi vertex and not primary vertex
-// - distance xi-V0 added in the container
-// - AOD analysis developed (January 2012)
-// - cut on TPC clusters as a parameter
-// - cut on min pt of daughter tracks added (parameter+control histos)
-// - cut on pseudorapidity for daughter tracks as a parameter (+control histos for Xi-)
-// December2014
-// - de-commented the v0 and cascade revertexers
-// - added methods to define the set of cuts used in the V0 and cascade re-vertexers
