What is the current situation in Yade? Particles do not "hang" on 
facets, or you are still implementing meshed surfaces?
Btw, I remember when I wrote a 2D equivalent ((*) more or less) of 
facets, it needed a way to keep the history of contacts when they were 
sliding or rolling from one facet to an edge, and from the edge to 
another facet. Is there something like this with Yade's facets, or do we 
create new interactions for each new pair? I never looked into that part 
of the code.
