// Class for PID selection with calorimeters
// The Output of the main method GetIdentifiedParticleType is a PDG number identifying the cluster, 
// being kPhoton, kElectron, kPi0 ... as defined in the header file
//   - GetIdentifiedParticleType(const AliVCluster * cluster) 
//      Assignes a PID tag to the cluster, right now there is the possibility to : use bayesian weights from reco, 
//      recalculate them (EMCAL) or use other procedures not used in reco.
//      In order to recalculate Bayesian, it is necessary to load the EMCALUtils library
//      and do SwitchOnBayesianRecalculation().
//      To change the PID parameters from Low to High like the ones by default, use the constructor 
//      AliCaloPID(flux)
//      where flux is AliCaloPID::kLow or AliCaloPID::kHigh
//      If it is necessary to change the parameters use the constructor 
//      AliCaloPID(AliEMCALPIDUtils *utils) and set the parameters before.

//   - GetGetIdentifiedParticleTypeFromBayesian(const Double_t * pid, const Float_t energy)
//      Reads the PID weights array of the ESDs and depending on its magnitude identifies the particle, 
//      executed when bayesian is ON by GetIdentifiedParticleType(const AliVCluster * cluster) 
//   - SetPIDBits: Simple PID, depending on the thresholds fLOCut fTOFCut and even the
//     result of the PID bayesian a different PID bit is set.
