* proposed by Maya STAVRIANAKOU)
*
* An FSimEvent contains, at filling time, only particles from the
* GenEvent it is being filled with. Material Effects then
* update its content, so that it resembles the output of Geant
* at the end of the material effect processing.
*
* Important : All distances are in mm
