//            AliAnalysisTaskQAMultistrange 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
//                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
