// History:
// -----------
// 08 Oct 2008   L. Pandola   1st implementation. Migration from EM process 
//                            to EM model
// 21 Oct 2009   L. Pandola   Remove un-necessary methods and variables to handle
//                            AtomicDeexcitationFlag - now demanded to G4VEmModel
// 24 May 2011   L. Pandola   Renamed to Penelope01 (obsolete version)
