 temporary selection: PID AS USED FOR D0 by Andrea Rossi (up to 28/06/2010)

 d must be a AliAODRecoDecayHF2Prong object
 returns 0 if both D0 and D0bar are rejectecd
         1 if D0 is accepted while D0bar is rejected
         2 if D0bar is accepted while D0 is rejected
         3 if both are accepted
 fWhyRejection variable (not returned for the moment, print it if needed)
               keeps some information on why a candidate has been
               rejected according to the following (unfriendly?) scheme
             if more rejection cases are considered interesting, just add numbers

      TO BE CONSIDERED WITH A GRAIN OF SALT (the order in which cut are applied is relevant)
              from 20 to 30: "detector" selection (PID acceptance)
                                                  26: TPC refit
                                                  27: ITS refit
                                                  28: no (TOF||TPC) pid information (no kTOFpid,kTOFout,kTIME,kTPCpid,...)

              from 30 to 40: PID selection
                                                  31: no Kaon compatible tracks found between daughters
                                                  32: no Kaon identified tracks found (strong sel. at low momenta)
                                                  33: both mass hypotheses are rejected

 This method combines the tracks, PID and cuts selection results

 Note: this method is temporary
 Additional cuts on decay lenght and lower cut for d0 norm are applied using vertex without candidate's daughters

STANDARD CUTS USED FOR 2010 pp analysis
dca cut will be enlarged soon to 400 micron

 Cuts for 2010 pp 7 TeV data analysis in Ntracklets bins (vs multiplicity)

 STANDARD CUTS USED FOR 2011 pp analysis at 2.76TeV

 Final CUTS USED FOR 2010 PbPb analysis of central events
 REMEMBER TO EVENTUALLY SWITCH ON

 CUTS USED FOR D0 RAA for the CENTRALITY RANGE 20-80%
