Upgrade of the Cascade envt :

1. AddTaskCheckCascade :

    - lMasterJobFlagSession, argument passed by value,

    - removal of SetRealDataFlag();

2. AddTaskCheckPerformanceCascade :

    - lMasterJobFlagSession, argument passed by value;

3. AliAnalysisTaskCheckCascade :

  3.1 Management of the trigger conditions : profit from (AliPhysSel+AliBackgroundSelection)

        --> hyp from now on : AliPhysicsSelectionTask used in front of CheckCascade;

  3.2 Removal of fRealDataFlag

  3.3 Launch the V0/Cascade vertexer at the beginning of the ESD analysis (part commented)

  3.4 Assess the event multiplicity via the number of TPCrefit tracks

        --> quantity used to fill the PID CFContainers + CascCuts CFContainer;

  3.5 Quality cuts possibilities (hardcoded bool to enable/disbale within the code...)

       --> On primary vertex :
             * | z(best prim vtx) | < 10 cm
             * remove TPC-only prim. vertex

       --> On quality of the 3 daughter tracks:
             * ask for TPCrefit

             * ask for 80 clusters in TPC

       --> On track indices : remove candidates with daughter tracks used twice within the candidate

   3.6 PID parametrisation of the TPC

       -->update lAlephParam for GSI Pass5/Grid Pass2 of 900GeV real data (A.Kalweit)

4. AliAnalysisTaskCheckPerformanceCascade

   4.1 Management of the trigger conditions : profit from (AliPhysSel+AliBackgroundSelection) on MC

       --> hyp from now on : AliPhysicsSelectionTask used in front of CheckPerfCascade;

   4.2 Launch the V0/Cascade vertexer at the beginning of the ESD analysis (part commented)

   4.3 Quality cuts possibilities (hardcoded bool to enable/disbale within the code... like CheckCascade)

   4.4 PID CFContainers :

       --> counterpart of what can be found into CheckCascade (Comb + TPC PID), but for MC-associated candidates

   4.5 Definition of findable : pt(proton) > 0.5 moved to > 0.3 GeV/c
