// Steer TRD QA train for Reconstruction (Clusterizer, Tracking and PID).
// 
// Usage:
//   AddTrainPerformanceTRD.C(MC, friends, tasks)
//   tasks : "ALL" or one/more of the following:
//     "EFF"  : TRD Tracking Efficiency 
//     "EFFC" : TRD Tracking Efficiency Combined (barrel + stand alone) - only in case of simulations
//     "MULT"  : TRD single track selection
//     "RES"  : TRD tracking Resolution
//     "CLRES": clusters Resolution
//     "CAL"  : TRD calibration
//     "ALGN" : TRD alignment
//     "PID"  : TRD PID - pion efficiency 
//     "PIDR" : TRD PID - reference data
//     "DET"  : Basic TRD Detector checks
//     "NOFR" : Data set does not have AliESDfriends.root 
//     "NOMC" : Data set does not have Monte Carlo Informations (real data), so all tasks which rely
//              on MC information are switched off
//
// In compiled mode : 
// Don't forget to load first the libraries
// gSystem->Load("libMemStat.so")
// gSystem->Load("libMemStatGui.so")
// gSystem->Load("libANALYSIS.so")
