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