952	16 Oct 06: L.Urban
953	- new msc version (G4MultipleScattering, G4UrbanMscModel):

955	- min. steplimit in 8.1: tlimitmin = max(lambda/25, 5 nanometer)
956	now : tlimitmin = max(lambda/25, 1.01*stepmin)
957	where stepmin ~ lambda elastic
958
959	- possibility to have extreme small step(s) before boundary crossing
960	this feature is not active by default;
961	it can be activated by setting the data member "skin" to a
962	non-negative value, steplimit = stepmin, if the distance to the boundary
963	(in the original direction) is smaller than skin*stepmin;
964
965	- the step restriction is weaker for particles with higher energy,
966	i.e. bigger effective facrange value is used in this case
967	in 8.0/8.1 this 'scaling' depends on Tkin, new version :
968	scaling depends on lambda, giving smaller material dependence
969
970	- Angular distribution has been changed:
971
972	- single/plural scattering for step <= stepmin
973	(in this case t = z + no lateral displacement)
974

976
977	- tail of the distribution has been modified, now the parameter
978	describing the tail is material (i.e. Z) dependent
