+/// \class AliMUONDigitizerV3
+/// The digitizer is performing the transformation to go from SDigits (digits
+/// w/o any electronic noise) to Digits (w/ electronic noise, and decalibration)
+///
+/// The decalibration is performed by doing the reverse operation of the
+/// calibration, that is we do (Signal+pedestal)/gain -> ADC
+///
+/// Note also that the digitizer takes care of merging sdigits that belongs
+/// to the same pad, either because we're merging several input sdigit files
+/// or with a single file because the sdigitizer does not merge sdigits itself
+/// (for performance reason mainly, and because anyway we know we have to do it
+/// here, at the digitization level).
