// History:
// -----------
// 15 Feb 2010   L. Pandola   1st implementation. 
// 18 Mar 2010   L. Pandola   Removed GetAtomsPerMolecule(), now demanded 
//                            to G4PenelopeOscillatorManager
// 24 May 2011   L. Pandola   Renamed (make v2008 as default Penelope)
// 10 Jun 2011   L. Pandola   Migrated to the new AtomDeexcitation interface
// 09 Oct 2013   L. Pandola   Migration to MT
