Computes the solution to the attitude determination problem using
   the cone intercept method. Only uses sun angles and chordwidths.
   Requires the corresponding sun vectors and nadir vectors. 

   The 4th input can either be leading edge times or chordwidths. 
   The last input must be set to either 'time' or 'angl'. The default is 'time'.
   To input chordwidths, set the 5th input (tte) to be empty.
   [ra,dec,rd] = ConeInt( usun, unadir, sa, tle_cw, tte, cant, eradius,
                          spinrate, threshold, type )

   usun         (3,n)     Unit sun vector
   unadir       (3,n)     Unit nadir vectors
   sa           (1,n)     The angle between the sun line and the spin axis
   tle_cw       (1,n)     Leading edge times (sec) or chordwidths (rad)
   tte                    Trailing edge time (sec) (Set to empty for chordwidths)
   cant                   Cant angle (rad)
   eradius      (1,n)     Angular radius of the rearth (rad)
   spinrate               Spin rate (rad/sec)
   threshold              Threshold chord width (rad)
   type                   'time' = leading and trail edge times entered (default)
                          'angl' = chordwidths and dihedral angles entered

   ra                     Right ascension of the spin axis
   dec                    Declination of the spin axis
   rd           (2,n)     [Right Ascension;Declination] vector
