We have added the possibility to perform an
event tag cut to select muons in the dimuon spectrometer.
In fact the setter AliEventTagCuts::SetNMuonRange(), which was already
available in aliroot, is based on the muon selection done according to the
global PID, therefore it counts muons both in the central barrel and in the
dimuon spectrometer.
To select only the forward muons, we have implemented the setter
SetNFWMuonRange(). The selection of the muons, in this case, is based on the method AliAODTracks::IsMuonTrack().
