+/// \class AliMUONDigit
+/// A class representing a digit 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 (either real digits or
+/// simulated ones but including electronic noise and de-calibration, to
+/// closely ressemble real ones).
