1200 - Corrected the last update of G4Transportati    
1201   value of the spin in the cases where a part    
1202   or a charged particle was not in a field.

1215 ------------------------------                   
1216 - G4Transportation modified to use new FieldT    
1217   Energy from it.                                
1218   This new FieldTrack together with changes i    
1219   classes implement the momentum vector as in    
1220   the velocity.                                  
1221   So this tag requires                           
1222   - new geometry/magneticfield tag "field-V03

1326 - Modified it to add re-computation of Safety    
1327   when the safety would become negative.  Thi    
1328   to benefit from a realistic (geometrical) v    
1329   request to do this was from EM physics

1332 ------------------------------                   
1333 - The safety we is now generalised to mean th    
1334   processes. The AlongStepGPIL input value is    
1335   previous step's geometrical safety.            
1336   So the transportation must recalculate the
