+//  Description:
+//    The process that triggers parameterised simulations
+//    if any.
+//
+//  History:
+//  Feb 98: Parallel geometry sensitivity. MoraDeFreitas.
+//  Oct 97: "Fast" replaces "Parameterisation" in class/method names. 
+//          (release B.00 for parameterisation). MoraDeFreitas.
+//  Aug 97: First implementation. Verderi && MoraDeFreitas.
+//  Apr 98: modified for new particle change.  H.Kurashige
