83216 Oct 06: L.Urban
833- new msc version (G4MultipleScattering, G4UrbanMscModel):
834  -  Stepping has been modified:
835     -  min. steplimit in 8.1: tlimitmin = max(lambda/25, 5 nanometer)
836                  now        : tlimitmin = max(lambda/25, 1.01*stepmin)
837           where stepmin ~ lambda elastic
838
839     - possibility to have extreme small step(s) before boundary crossing
840       this feature is not active by default;
841       it can be activated by setting the data member "skin" to a
842       non-negative value, steplimit = stepmin, if the distance to the boundary
843       (in the original direction) is smaller than skin*stepmin;
844
845     - the step restriction is weaker for particles with higher energy,
846       i.e. bigger effective facrange value is used in this case
847       in 8.0/8.1 this 'scaling' depends on Tkin, new version :
848       scaling depends on lambda, giving smaller material dependence
849
850  - Angular distribution has been changed:
851
852     - single/plural scattering for step <= stepmin
853       (in this case t = z + no lateral displacement)
854
855     - parameter theta0 has been (sligtly) modified
856
857     - tail of the distribution has been modified, now the parameter
858       describing the tail is material (i.e. Z) dependent
