0013 /** The FAMOS SimEvent: inherits from FBaseSimEvent,
0014  *  where the latter provides FAMOS-specific event features (splitting
0015  *  proposed by Maya STAVRIANAKOU)
0016  *
0017  * An FSimEvent contains, at filling time, only particles from the 
0018  * GenEvent it is being filled with. Material Effects then 
0019  * update its content, so that it resembles the output of Geant
0020  * at the end of the material effect processing.
0021  *
0022  * Important : All distances are in mm
