// runEMCalJetAnalysis.C
// =====================
// This macro can be used to run a jet analysis within the EMCal Jet Framework.
//
// Examples:
// -> Analyze ESDs from the pA pilot run on the AliEn grid with your task in AnaClass.cxx/.h
//     dataType = "ESD", useGrid = kTRUE, pattern = "*ESDs/pass2/*ESDs.root", addCXXs = "AnaClass.cxx", 
//     addHs = "AnaClass.h", gridDir = "/alice/data/2012/LHC12g", gridMode = "full", runNumbers = "188359 188362"
//     
// -> Analyze AODs (up to 96 files) locally given in files_aod.txt
//     dataType = "AOD", useGrid = kFALSE, numLocalFiles = 96
//
// MERGING ON ALIEN
// ++++++++++++++++
// If you run on the grid, you can monitor the jobs with alimonitor.cern.ch. When enough of them are in DONE state,
// you have to merge the output. This can be done automatically, if you just change the gridMode to "terminate" and
// give the EXACT name of the task whose output should be merged in uniqueName.
//
