Hi

The more I think the less I understand what is happening in 
InteractingBox2InteractingSphere4SpheresContactGeometry.

Vaclav, you were right, I didn't change anything in your code in 
principle (except a small mistake that I introduced, I just corrected it 
in svn, but it has no influence on what follows).

Now I'm lost... I did run version 1194 and 1185, and I saw big 
differences in the results regarding sphere-box interactions.

Vaclav, could you have a look at the cpp file in version 1185 (your 
version) and try to see a difference with the last revision. I really 
can't see one (in the maths I mean, of course the code is a bit different).

Just to be sure, in mathematics, those definitions of b are equivalent 
right? :
# a=x, then b=a
# a=-x, then b=-a
please, tell me that b=x in both cases :-P

Bruno
