/// \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)
///
/// (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.
+///
