28 // Class description:
29 //
30 // This process is used to split the length and energy
31 // of a step in a regular structure into sub-steps, and to
32 // call the scorers for each sub-volume.
33 // It invokes sensitive detectors assigned in the *mass* world.
34 //
35 // Design and first implementation: J.Apostolakis, M.Asai - 2010
