/// \brief Macro for reading trigger raw data
///
/// \author Ch. Finck, Subatech, April 2006
///
/// Implement "digits" iterator.
/// This macro is interface with AliRawReader for RAW.
/// The different stucture of the patload are readout and stored in TClonesArray
/// with AliMUONRawStreamTrigger class.
/// The macro just simply reads 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.
/// The DATE format reading is no more supported please use the MUONTRGda code.
