CW2Roll:

Path: SC/Sensor

% Converts the output from a conical scanning sensor to roll. 
 Gives two outputs to account for the nadir angle ambiguity.

--------------------------------------------------------------------------
   Form:
   roll = CW2Roll( scanAngle, cant, uSpin, uPitch, earthRadius, chordwidth  )
--------------------------------------------------------------------------

   ------
   Inputs
   ------
   scanAngle     (:) 	Measured scan angle (rad)
   cant          (1,1)	Sensor element cant angle from the spin-axis (rad)
   uSpin         (3,1)	Sensor spin-axis
   uPitch        (3,1)	Pitch axis
   earthRadius   (1,1)	Angular radius of the earth (rad)
   chordwidth    (:)  	Measured chordwidth (rad)

   -------
   Outputs
   -------
   roll          (2,:)  Roll angle (rad)
