% Compute the pulse pair delay for a Spin Precession Maneuver.
   Computes the delay from the sun sensor pulse given the spin-axis,
   sensor boresight and the thruster torque axis. The delay is measured
   from the time the sensor sees the sun to the time the thruster must 
   fire.

   Form:
   [delay, w] = PPDelay( azimuth, pulsewidth, t, h, s, spinRate, tauRise, tauFall )
