/// REVISION HISTORY:\n
///     24 Mar 2010 : Gabriel Orebi Gann - Correct code to write
///                   to PMTCal objects instead of PMTUnCal
///                 - Remove pedestal smearing
///                 (this will go in to the `uncalibrator') \n
///     25 Mar 2010 : Gabriel Orebi Gann - Remove digitisation
///                   from `truth' PMTCal MC \n
///     26 Mar 2010 : Gabriel Orebi Gann - Set ChanFlags to 0 for each
///                   new PMTCal object, and randomly select CellID
///                   from 0-15. \n
///     29 Mar 2010 : Gabriel Orebi Gann - Add call to uncalibrator
///                 - Move digitisation of PMTUnCal to
///                   Uncal.UnCalibrateEvent routine \n
///     27 Apr 2010 : G Orebi Gann - Write to PMTTruth objects, instead
///                   of PMTCal \n
///     28 Apr 2010 : G Orebi Gann - Correct PMT hit times \n
///     12 May 2010 : G Orebi Gann - Use 50MHz clock time for GT \n
///     03 Mar 2011 : G Orebi Gann - Create PMT objects by type
///                   (normal, owl etc) \n
///      30 Sep 2016 : W Heintzelman - Add code to tabulate photoelectron
///                    generation in special runs to calculate PMT
///                    effectiveness tables
///     22 Oct 2016 : N Barros - Added check that there there is a MC branch to apply the
///                            processor, otherwise the processor would silently crash.
///     09 Nov 2016 : N Barros - Moved everything RATDB related from constructor to BeginofRun
///
