// Modified:
// 23.11.2005 G.Folger: migration to non static particles
// 08.06.2006 V.Ivanchenko: remove stopping
// 20.06.2006 G.Folger: Bertini applies to Kaons, i.e. use SetMinEnergy instead of SetMinPionEnergy
// 25.04.2007 G.Folger: Add code for quasielastic
// 10.12.2007 G.Folger: Add projectilediffrative option for proton/neutron, off by default
// 31.10.2012 A.Ribon: Use G4MiscBuilder
// 19.03.2013 A.Ribon: Replace LEP with FTFP
