[ODE] getting bodies acceleration

[Robert Rose]

I'm new to ODE, but doesn't F=ma? :-)  Wouldn't this work:

dBodyGetForce () / mass

?

"Return the current accumulated force ... vector. The returned pointers 
point to an array of 3 dReals. The returned values are pointers to 
internal data structures, so the vectors are only valid until any 
changes are made to the rigid body system."
