[ODE] Question about moving a Submarine.

[Tyler Streeter]

You can use a damped spring equation for linear and angular motion
(i.e. a PD controller).  You would then simply set the desired
position and orientation (and a few spring and damping constants) and
let the spring calculate the force required to the submarine into the
desired position/orientation.

Here's some source code that does this:
