Geant4 FTFP_EMV hadronic model

FTFP, FTFP_EMV, and FTFC (see and recommending physics lists)

In FTF physics lists, a different string model is used. The FTF model is based on the FRITIOF description of string excitation and fragmentation. This model is currently (releases 8.3, and 9.0) being improved with further refinements forseen for the next release of Geant4.
