[ODE] Simple Ball-Interaction

[Jaroslav Sinecky]

I don't think you need inverse dynamics for this. The quick solution 
you're looking for could be simply using a geom with some very heavy 
(relatively to other bodies) body attached and moving this body around 
by setting directly position and velocity.

Collisons between bodyless geom and other geoms with body should be 
detected and working and it would be the ideal solution if there would 
be a way how to specify that the bodyless geom is actualy moving, ie. 
velocity of contact point. (BTW, shouldn't be difficult to implement 
this, eh?)
