//
//  Description:
//    This process is used to split the length and energy 
//   of a step in a regular structure into sub-steps, and to 
//   call the scorers for each sub-volume.
//    It invokes sensitive detectors assigned in the *mass*
//   world.
//
//  Design and first implementation: J. Apostolakis / M.Asai 2010
