SUMMARY :  Commit of the 900 GeV strangeness paper
    histo dE/dx in TPC
+ binning change
+ TPC PID requirements become default for filling CascCuts containers
---------------------------
1. CheckCascade :
* TH1F : introduction histo fHistCascadeMultiplicityForTrigEvtAndZprimVtx
* TH2F : introduction histo dE/dx in the TPC ( f2dHistTPCdEdxOfCascDghters )
* removal of the TH3F used for Combined PID (redundance with the PID CFContainers)
* Binning change :
       - primary vertex in x,y and z (fHistPosBestPrimaryVtxZForSelEvt, ...)
       - rapidity binning: y in [-1.1;1.1] instead of [-1.2;1.2] (f3dHistXiPtVsEffMassVsY... + CFContainers fCFContCascadePID...)
       - pt binning
* Trigger Selection : bit mask comparison (compliance with the new trigger selection of rev. 42530)
* PID :
        - default TPC cut at 4-sigma (+ commented : possibility to cut at 3-sigma below pt=X / 5-sigma above)
        - TH1F selection histos = filled if TPC pid requirements are satisfied
* PID CFContainers : Multiplicity dimension = now based on SPD tracklets instead of TPCrefit tracks
* fCFContCascadeCuts :
        - user binning + large first/last bin to avoid underflow/overflow
            (---> Projection pb with under-/overflow in TAxis for THnSparse  !!!)
        - container filled if TPC pid requirements are satisfied
* Angular correlation : THnSparseF = filled if TPC pid requirements are satisfied

2. CheckPerformance
* Binning change :
        - (x 2) for Inv Mass plots (200 -> 400 bins for Xi, 250 -> 500 bins for Omega)
        - rapidity binning: y in [-1.1;1.1] instead of [-1.2;1.2] (f2dHistAsMCGenPtVsGenYXi..., ...)
* PID CFContainers : Multiplicity dimension = now based on SPD tracklets instead of TPCrefit tracks
* Definition of findable released to looser cuts :   lBach->Pt() < 0.150   lDghtBarV0->Pt() < 0.250        lDghtMesV0->Pt() < 0.150
* Trigger Selection : bit mask comparison (compliance with the new trigger selection of rev. 42530)
* PID :
        - default TPC cut at 4-sigma (+ commented : possibility to cut at 3-sigma below pt=X / 5-sigma above)
* fCFContAsCascadeCuts :
        - user binning + large first/last bin to avoid underflow/overflow
            (---> Projection pb with under-/overflow in TAxis for THnSparse  !!!)
        - container filled if TPC pid requirements are satisfied
