// AliAODEventInfo: a class for AODs for the MUON Arm of the ALICE Experiment
// Author: P. Cortese, Universita' del Piemonte Orientale in Alessandria and
// INFN of Torino - Italy
//
// This class provides additional information about the AliAODEvent, some
// of this is specific to MUON. The information stored in this class will 
// follow the evolution of the framework (i.e. some data members  may be 
// moved into the header in the future).
// Currently it stores the beam energy and the information needed to decode
// the trigger pattern (which are the bits corresponding to the different
// muon triggers).
