+ Creation of the MUON-AOD from the standard AOD
+ Roberta ARNALDI, Enrico SCOMPARIN Torino
+---------------------------------------------------------------
+
+Code to produce a muon-AOD, i.e. a replica of the standard AOD containing only events where
+at least one muon is present
+
+1) AnalysisTrainFromStandardToMuonAODLocal.C --> macro to produce the MUON-AOD (it runs locally)
+2) AliAnalysisTaskFromStandardToMuonAOD.h --> analysis task to replicate the AOD content for interesting events
+3) AliAnalysisTaskFromStandardToMuonAOD.cxx --> analysis task to replicate the AOD content for interesting events
+4) libPWG3muon.pkg
+5) PWG3muonLinkDef.h
+
+- The input files are the ESD (used only for tag creation) and the standard AOD.
+ Tags files are created from all the ESD/AOD files placed in a directory,
+ given as an argument to the macro, and in its subdirectories.
+- The selection of the muon events is based on the AOD tags.
+- The contents of the MUON-AOD can be defined by the user in the AnalysisTrainFromStandardToMuonAODLocal.C
+ macro with some settings as
+ SetNeedsTracksBranchReplication(), SetNeedsVerticesBranchReplication()
+ (defined in STEER/AliAODHandler.h)...
