-// AliAnalysisTaskCheckCascadePbPb class
-// Origin AliAnalysisTaskCheckCascade
-// This task 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, antonin.maire@ires.in2p3.fr
-// Modified for PbPb analysis: M. Nicassio Feb 2011, maria.nicassio@ba.infn.it
