SubGoals:

--------------------------------------------------------------------------
   Subtract one set of geometric goals from the other.

   Given the geometry of A and the geometry of B, compute the geometry 
   of B with respect to A.

   Since version 7.
--------------------------------------------------------------------------
   Form:
   gBA = SubGoals( e, nu, gA, gB, n );

   e                (1)      Eccentricity
   nu               (1)      True anomaly   [rad]
   gA               (.)      Geometric goals of A
   gB               (.)      Geometric goals of B
   n                (1)      Mean orbit rate
