[ODE] collision matrix

[Bram Stolk]

Of the open intersection tests:

- ray vs ray is indeed silly... they dont intersect due
  to their infinite thin-ness.
- plane vs trimesh is a simple problem, especially when
  done naively by iterating through triangles.
- cyl vs cyl is a very hard one. I'm affraid it takes
  a mathematics Phd to do this properly. I did see a
  paper with an algorithm for this though, floating on the net.
  No sample code though.
- cyl vs capsule is probably just as hard.
- cyl vs ray is simple, and in fact, the code
  is already there for solving the cyl/plane
  case, but not exposed to the engine.

I suppose that the meaning is "no, and will not". It's not reasonable to 
collide rays between them ( Not in rigid physics simulation)
