[ODE] get triangle index of a trimesh

In my copy of the manual, on page 66, section 10.7.6, it talks about the 
callbacks that will tell you which triangles are hit during collision; 
it's an old version, so it may have moved around. Search for 
dTriCallback and dTriRayCallback to locate it.

If you have read this part, and experimented with the code, and it still 
won't let you do what you want, please post a description of what you 
have tried, and why it didn't work for you.
