// This macro is interface with AliRawReader for RAW
// The different stucture of the patload are readout and stored in TClonesArray
// with AliMUONRawStreamTrigger classe.
// The macro just simpy read again the TClonesArray contents.
// The parameter of each structure could be seen in the container classes
// AliMUONDarcHeader, AliMUONRegHeader, AliMUONLocalStruct.
// The class AliMUONDDLTrigger manages the structure containers.
// The number of structures in the rawdata file could be set.
