c       This routine cleans up all the parallel environment on which
c      parallel Geant is layered. No parallel Geant routines should
c      be called after calling gplast.
c       To ensure that compatibility with all current MPI implementations
c      we ask that no code is executed after calling gplast.
c       To implement this choice we call 'STOP' at the end !!
