/// \class AliMUONRawWriter
/// MUON Raw Data generaton in ALICE-MUON
/// Raw data structure could be found in Alice-note.
///
/// Implemented non-constant buspatch numbers for tracking

/// (Ch. Finck, dec 2005)
///
/// Digits2Raw:
/// Generates raw data for MUON tracker and finally for trigger
/// Using real mapping (inverse) for tracker
/// For trigger there is no mapping (mapping could be found in AliMUONTriggerCircuit)
/// Ch. Finck, July 04
/// Use memcpy instead of assignment elt by elt
/// Introducing variable DSP numbers, real manu numbers per buspatch for st12
/// Implemented scaler event for Trigger
/// Ch. Finck, Jan. 06
/// Using bus itr in DDL instead of simple incrementation
/// treat correctly the DDL & buspatch for station 3.
/// Using informations from AliMUONTriggerCrateStore for 
/// empty slots and non-notified cards in trigger crates.
