SunBeta:

--------------------------------------------------------------------------
   Computes the sun beta angle (i.e. elevation out of the orbit plane)
   given the sun unit vector (or right ascension and declination),
   the right ascension of the ascending node and the inclination of the
   orbit.

   Type SunBeta for a demo.

   Since version 1.
--------------------------------------------------------------------------
   Form:
   beta = SunBeta( i, uSun, rA )
--------------------------------------------------------------------------
