-/// \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).
-///
-/// August 2011. In order to remove the need for specific MC OCDB storages,
-/// we're introducing a dependence of simulation on AliMUONRecoParam (stored
-/// in MUON/Calib/RecoParam in OCDB), which is normally (or conceptually, if
-/// you will) only a reconstruction object. That's not a pretty solution, but,
-/// well, we have to do it...
-/// This dependence comes from the fact that we must know how to decalibrate
-/// the digits, so that the decalibration (done here) - calibration (done during
-/// reco) process is (as much as possible) neutral.
-///
