AsteroidProxOpsDemo:

 Simulate proximity operations around an asteroid.

 The spacecraft has 3-axis thruster control. Ideal attitude sensing is
 assumed. The PID controller produces a torque vector which is applied
 directly to the spacecraft. The control keeps the body X axis aligned
 towards the asteroid as the maneuver takes place. The initial relative
 velocity is zero; it takes about 3 minutes to achieve the target
 velocity, and another few minutes for the attitude rates to settle.

 The 3D plot shows the resulting trajectory along with the force vector
 in green and the sensor vector (body X) in red.

 Since version 2014.1
