// History:
// --------
// 26 Nov 2008 L Pandola Migration from process to model
// 17 Apr 2009 V Ivanchenko Cleanup initialisation and generation of secondaries:
// - apply internal high-energy limit only in constructor
// - do not apply low-energy limit (default is 0)
// - added MinEnergyCut method
// - do not change track status
// 19 May 2009 L Pandola Explicitely set to zero pointers deleted in
// Initialise(), since they might be checked later on
// 21 Oct 2009 L Pandola Remove un-necessary fUseAtomicDeexcitation flag - now managed by
// G4VEmModel::DeexcitationFlag()
// Add ActivateAuger() method
//
