This writes an event out to the HEPEVT common block. The daughters field is NOT filled, because it is possible to contruct graphs for which the mothers and daughters cannot both be make sequential. This is consistent with how pythia fills HEPEVT (daughters are not necessarily filled properly) and how IO_HEPEVT reads HEPEVT.
