// Author: 2010 Tatsumi Koi, Gunter Folger
//   created from G4HadronPhysicsFTFP_BERT
//
// Modified:
//
// 2020.05.07 A.Ribon: Used the newly introduced G4HyperonBuilder
// 2019.08.01 A.Ribon: Replaced explicit numbers for the energy transition
//                     region with values taken from G4HadronicParameters
// 2014.08.05 K.L.Genser: Added provisions for modifing the Bertini to
//                        FTF transition energy region
// 2024.11.19 D.M.Wright: Removed LEND inelastic neutron model,
//                        is now done in G4HadronPhysicsLEND
