0029 //
0030 // This process is used to split the length and energy
0031 // of a step in a regular structure into sub-steps, and to
0032 // call the scorers for each sub-volume.
0033 // It invokes sensitive detectors assigned in the *mass* world.
0034 //
0035 // Design and first implementation: J.Apostolakis, M.Asai - 2010
