SubOrbDistance:

--------------------------------------------------------------------------
   Compute the min angular distance (around the Earth) that connects 2 pts.
   Since version 1.0
--------------------------------------------------------------------------
   Form:
   [angleDist,range] = SubOrbDistance( lat0, lon0, latF, lonF );
--------------------------------------------------------------------------

   ------
   Inputs
   ------
