// Class G4MassWeioghtWindowProcess
//
// Class description:
//
// Used internally by weight window technique in the "mass" geometry.
// This process is a forced post step process. It will apply
// weight window biasing on boundaries, collisions
// or both according to the G4PlaceOfAction argument.
// Author: Michael Dressel (Michael.Dressel@cern.ch)
