I did not yet have time to test it but from a quick look at the source 
it seems it might lead to slower calculations in cases of:

- relatively few masses
- situations where grouping works very well (like single masses 
colliding with grid structures).

It would be useful to have some numbers actually comparing speed in such 
situations.  Also you replaced the exisiting collision method with the 
new technique - it would probably have been better to introduce it as an 
alternative method so you can compare them more easily.
