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