// History:
// -----------
// 23 Nov 2010  L. Pandola       1st implementation
// 24 May 2011  L. Pandola       Renamed (make default Penelope)
// 13 Mar 2012  L. Pandola       Made a derived class of G4VEmAngularDistribution
//                               and update the interface accordingly
// 18 Jul 2012  L. Pandola       Migrate to the new interface of G4VEmAngularDistribution
// 03 Oct 2013  L. Pandola       Migration to MT
