/// REVISION HISTORY:\n
///
///  17-07-2013 : N. Barros : Modified the class to derive from DecayChain_Gen instead of
///                           GLG4Gen. This solves the timing problem with timing of pileup events.
///  14-03-2017 : N. Barros : Small modification to comply with base generator changes.
///
///
///  \details  Generates Co57 decays in the gas volume of the Co57
///           source for any source position.  Requires source
///           geometry to be loaded.  No generator position
///           modifications accepted.
