DSunCone:

--------------------------------------------------------------------------
   Compute possible right ascensions and declinations given
   a sun angle as a function of the angular distance from the 
   nominal orientation. 
--------------------------------------------------------------------------
   Form:
   [rA, dec, phi] = DSunCone( uSun, rAI, decI, beta )
--------------------------------------------------------------------------

   ------
   Inputs
   ------
   uSun         (3,1)     Sun Vector
   rAI                    Nominal right ascension (rad)
   decI                   Nominal declination (rad)
   beta                   Sun angle (rad)

   -------
   Outputs
   -------
   rA            (:)     Right Ascension (rad) 
   dec           (:)     Declination  (rad)
