+/// \class AliMUONDigit
+/// A class representing a digit (with MC information if possible)
+/// in the MUON spectrometer either in tracking or trigger chambers.
+///
+/// A digit holds the signal (proportional to a charge) on a pad
+/// (or strip).
+/// 
+/// This class is used to represent either sdigits (purely simulated digit, 
+/// with no electronic noise whatsoever) or digits (simulated ones but 
+/// including electronic noise and de-calibration, to closely ressemble real ones).
