24th Oct 2008 Peter Gumplinger (op-V09-01-08)
              use local G4OpProcessSubType.hh

21st Oct 2008 Peter Gumplinger (op-V09-01-07)
              add SetProcessSubType for G4OpAbsorption, G4OpBoundaryProcess,

              use signatures G4SwapPtr(T*& and G4SwapObj(T*
              in G4OpBoundaryProcess - to work with global-V09-01-12

15th Aug 2008 Peter Gumplinger (op-V09-01-05)
              replaced G4SwapPtr with G4SwapObj for Rindex
              in G4OpBoundaryProcess - serious error since op-V09-01-00
              (see also Problem Report 1020)

4th July 2008 Peter Gumplinger (op-V09-01-04)
              In G4OpWLS now SetTouchableHandle(aTrack.GetTouchableHandle())
              for the secondaries in the DoIt.

              G4LogicalSurface* Surface = NULL;

27th June 2008 Peter Gumplinger (op-V09-01-03)
               In G4OpBoundaryProcess changed unsafe cast

               following suggestion in bug-report #1014

6th June 2008 Peter Gumplinger (op-V09-01-02)
              G4OpRayleigh, G4OpWLS = trivial name changes:

5th June 2008 Peter Gumplinger (op-V09-01-00)
              G4OpBoundaryProcess: Removed G4Swap methods - replaced by
              G4SwapPtr. Removed G4IsotropicRand method - replaced by
              G4RandomDirection. Add commented code to change absorption
              at a dielectric/metal boundary into transmission.

29th Oct 2007 Peter Gumplinger (op-V09-00-01)
              In G4OpWLS.cc allow for the MeanNumberOfPhotons to be
              different from one, in case the constant property: 
              WLSMEANNUMBERPHOTONS is provided and, if it is, sample 
              NumPhotons with G4Poisson.

15th Oct 2007 Peter Gumplinger (op-V09-00-00)
              Add capability of calculating the reflectivity off a metal

              (Dept. of Physics - Iowa State Univ.)

11th May 2007 Gabriele Cosmo (op-V08-03-00)
              Use call to G4GeometryTolerance instead of kCarTolerance in
              G4OpBoundaryProcess.
              Requires tag "global-V08-03-00" and related tag set.

11th May 2006 Peter Gumplinger (op-V08-00-01)
              thanks to Andreia Trindade and Pedro Rodrigues, the WLS time
              delay can now be a delta function or exponential. New classes:
              G4VWLSTimeGeneratorProfile, G4WLSTimeGeneratorProfileDelta and
              G4WLSTimeGeneratorProfileExponential

12th August 2004 Peter Gumplinger (op-V06-02-01)
                In G4OpBoundaryProcess.cc: use GetMaterial from 
                G4StepPoint directly; apply/sample reflectivity and 
                Unified model reflection parameters only once even
                for rough dielectric/metal surfaces - i.e. not again
                even when reflected ray still points toward the
                surface - fixes problem report 654.

05th August 2004 Peter Gumplinger (op-V06-02-00)
                Allow for unified model reflectivity parameters 
                to also work in case of dielectric_metal surfaces;
                addresses in part problem report 654.
