//
//  Class for handling of ESD Muon track cuts 
//  (based on ANALYSIS/AliESDtrackCuts).
//
//  The class manages some kinematic cuts. Two methods
//  can be used to figure out if an ESD Muon track survives the cuts:
//  AcceptTrack which takes a single AliESDMuonTrack as argument and
//  returns kTRUE/kFALSE or GetAcceptedTracks which takes an AliESD
//  object and returns an TObjArray (of AliESDMuonTracks) with the tracks
//  in the ESD that survived the cuts.
