//  Description:
//    This procss takes a parallel world and limits a step
//   on the boundaries of volumes in the parallel world.
//    It invokes sensitive detectors assigned in the parallel
//   world.
//    It switches a material (and a region if defined) in the
//   assigned parallel world over the material (and the region)
//   in the mass world.
