      PURPOSE - PRODUCES THE SPECTRAL HARMONIC COEFFICIENTS WHICH ARISE
                WHEN THE INDEX IS "CONJUGATED", IE WHEN M IS NEGATIVE.
                THESE ARE (-1)**M TIMES THE COMPLEX CONJUGATE OF THE INPUT
                SPHERICAL HARMONIC COEFFICIENT.
 
 
      INPUT FILE...
       SPIN   = ANY COMPLEX ARRAY (MAX 20000 COMPLEX WORDS)
 
      OUTPUT FILE...
       SPOUT = SPHERICAL COEFFICIENT CONJUGATE OF SPIN
