1021	- Stepping has been modified:
1022	- min. steplimit in 8.1: tlimitmin = max(lambda/25, 5 nanometer)

1024	where stepmin ~ lambda elastic
1025
1026	- possibility to have extreme small step(s) before boundary crossing
1027	this feature is not active by default;
1028	it can be activated by setting the data member "skin" to a

1030	(in the original direction) is smaller than skin*stepmin;

1033	i.e. bigger effective facrange value is used in this case
1034	in 8.0/8.1 this 'scaling' depends on Tkin, new version :
1035	scaling depends on lambda, giving smaller material dependence
1036
