Well, i'm afraid i'm not too deep in ODE source at all and probably i'll
fail if i try to do that only by myself. It is good to make a plan about
that i.e. what exactly is needed - ode math simd support only or more
deep change. For collision libraries change i think it is better to ask
the authors of GIMPACT and OPCODE ... or developers that knows exactly
where we can speed up the stuff.
