// Usage:
//   makeResults.C("tasks?file_list")
//   tasks : "ALL" or one/more of the following separated by space:
//     "EFF"  : TRD Tracking Efficiency 
//     "EFFC" : TRD Tracking Efficiency Combined (barrel + stand alone) - only in case of simulations
//     "RES"  : TRD tracking Resolution
//     "CAL"  : TRD calibration
//     "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
//   file_list : is the list of the files to be processed. 
//     They should contain the full path. Here is an example:
// /lustre_alpha/alice/TRDdata/HEAD/1.0GeV/RUN0/TRD.TaskResolution.root
// /lustre_alpha/alice/TRDdata/HEAD/2.0GeV/RUN1/TRD.TaskResolution.root
// /lustre_alpha/alice/TRDdata/HEAD/3.0GeV/RUN2/TRD.TaskResolution.root
// /lustre_alpha/alice/TRDdata/HEAD/2.0GeV/RUN0/TRD.TaskDetChecker.root
// /lustre_alpha/alice/TRDdata/HEAD/2.0GeV/RUN1/TRD.TaskDetChecker.root
// /lustre_alpha/alice/TRDdata/HEAD/2.0GeV/RUN2/TRD.TaskDetChecker.root
// /lustre_alpha/alice/TRDdata/HEAD/2.0GeV/RUN0/TRD.TaskTrackingEff.root
//
// The files which will be processed are the initersaction between the 
// condition on the tasks and the files iin the file list.
