3.2 Patch SGVEVSIM : Event generator

This patch contains the code for event generation. It is to be considered as an example, to be replaced by user-code. It uses the JETSET generator LUEEVT which generates SM Z0 decays to quarks. If this is appropriate for the needs of the user, the patch can be used as is.
