/// Indranil Das (Adapted for runloader: Ch. Finck) july 05
///
/// Implemented non-constant buspatch numbers for tracking

/// (Ch. Finck, dec 05)
///
/// Add reader for scaler trigger events
/// Use memcpy instead of assignment elt by elt
/// (Ch. Finck, Jan 06)
///
/// Using new interface with AliMUONRawStreamTracker(Trigger)
/// (New interface of AliMUONRawReader class)
/// (further details could be found in Alice-note)
/// (Ch. Finck, March 06)
///
/// Add (S)Digit maker tracker (for free)
