+// AliAnalysisTaskCheckCascadepp276 class
+//
+// Origin AliAnalysisTaskCheckCascade which has four roles :
+// 1. QAing the Cascades from ESD and AOD
+// Origin: AliAnalysisTaskESDCheckV0 by Boris Hippolyte Nov2007, hippolyt@in2p3.fr
+// 2. Prepare the plots which stand as raw material for yield extraction (wi/wo PID)
+// 3. Supply an AliCFContainer meant to define the optimised topological selections
+// 4. Rough azimuthal correlation study (Eta, Phi)
+// Adapted to Cascade : A.Maire Mar2008, antonin.maire@ires.in2p3.fr
+// Modified : A.Maire Mar2010
+//
+// Adapted to PbPb analysis: M. Nicassio, maria.nicassio@ba.infn.it
+// Feb-August2011
+// - Physics selection moved to the run.C macro
+// - Centrality selection added (+ setters) and histos
+// - flag and setters added (CF container usage, vertex range)
+// - histo added and histo/container binning changed
+// - protection in the destructor for CAF usage
+// - AliWarning disabled
+// - number of tracklets from AOD also
+// - automatic settings for PID
+// September2011
+// - proper time histos/container added (V0 and Cascades)
+// - cosine PA V0 wrt Xi vertex in the container
+// November2011
+// - re-run V0's and cascade's vertexers (SetCuts instead SetDefaultCuts!!)
+// - problems of libraries on Grid --> code copied in the task (from AliRoot v5-10-AN
+// where new pt dependent V0's cosPA cut implemented by Iouri)
+// - AOD analysis part completed
+//
+//
+// Adapted to pp 2.76 analysis: D. Colella, domenico.colella@ba.infn.it
+// Gen-now 2012
+// - Physics selection re-moved here (mainly for normalization in the efficiency calcuation)
+// - Centrality selection deleted
+// -

+// 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)
+//
+//
+//
+// Adapted to pp 2.76 analysis: D. Colella, domenico.colella@ba.infn.it (Nov. 2012):
+// - added new and removed other histograms
+// - Physics selection moved here (mainly for normalization in the efficiency calcuation)
+// - Centrality selection deleted
+// - 3DHisto denominator moved before any event selection for Normalization
+// - injected and natural part of MC selection removed
+//
