ThrusterCommand:

Path: SCPro/ProControl

% Computes forces and torques for a set a thrusters using off-pulsing.
   Off-pulsing is used to produce delta-v and attitude control at the same
   time. 

   Inputs are a torque vector, the desired fraction of the time each
   thruster is on for delta-v, the set of thrusters to be used for
   attitude control and a data structure. If a feasible solution is not
   reached the control is not possible.

   Type

   ThrusterCommand

   for a demo that shows pure attitude control and also off-pulsing for
   delta-v and attitude control.

   Note that some options to simplex are hard coded:

   All thruster costs are the same
   The maximum constraint is not applied
