|
|
// Class 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
