	814	navigation (j.Apostolakis)

	817	- G4hMultipleScattering - new class configured for hadrons
	818	- G4eCoulombScatteringModel - set cross section const below 1 keV

	831
	832	20 Oct 06: L.Urban cleanup of msc
	833	- theta0 parameter for SampleCosineTheta is computed in a public
	834	function ComputeTheta0;
	835	- default value of skin = 0 (there is no small step with single scattering if
	836	skin <=0, and there are ~skin small steps if skin >0

	844
	845	16 Oct 06: L.Urban
	846	- new msc version (G4MultipleScattering, G4UrbanMscModel):
	847	- Stepping has been modified:
	848	- min. steplimit in 8.1: tlimitmin = max(lambda/25, 5 nanometer)
	849	now : tlimitmin = max(lambda/25, 1.01*stepmin)
	850	where stepmin ~ lambda elastic
	851
	852	- possibility to have extreme small step(s) before boundary crossing
	853	this feature is not active by default;
	854	it can be activated by setting the data member "skin" to a
	855	non-negative value, steplimit = stepmin, if the distance to the boundary
	856	(in the original direction) is smaller than skin*stepmin;
	857
	858	- the step restriction is weaker for particles with higher energy,
	859	i.e. bigger effective facrange value is used in this case
	860	in 8.0/8.1 this 'scaling' depends on Tkin, new version :
	861	scaling depends on lambda, giving smaller material dependence
	862
	863	- Angular distribution has been changed:
	864
	865	- single/plural scattering for step <= stepmin
