// 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.
