73116 Oct 06: L.Urban
732- new msc version (G4MultipleScattering, G4UrbanMscModel):
733  -  Stepping has been modified:
734     -  min. steplimit in 8.1: tlimitmin = max(lambda/25, 5 nanometer)
735                  now        : tlimitmin = max(lambda/25, 1.01*stepmin)
736           where stepmin ~ lambda elastic
737
738     - possibility to have extreme small step(s) before boundary crossing
739       this feature is not active by default;
740       it can be activated by setting the data member "skin" to a
741       non-negative value, steplimit = stepmin, if the distance to the boundary
742       (in the original direction) is smaller than skin*stepmin;
743
744     - the step restriction is weaker for particles with higher energy,
745       i.e. bigger effective facrange value is used in this case
746       in 8.0/8.1 this 'scaling' depends on Tkin, new version :
747       scaling depends on lambda, giving smaller material dependence
748
749  - Angular distribution has been changed:
750
751     - single/plural scattering for step <= stepmin
752       (in this case t = z + no lateral displacement)
753
754     - parameter theta0 has been (sligtly) modified
755
756     - tail of the distribution has been modified, now the parameter
757       describing the tail is material (i.e. Z) dependent
