TransformGeom2Hills:

--------------------------------------------------------------------------
   Transform geometric goals to hills-frame coordinates. 
   Works for either circular or eccentric orbits.

   Since version 7.
--------------------------------------------------------------------------
   Usage:
   xH = TransformGeom2Hills( el, g, nu );
--------------------------------------------------------------------------

   ------
   Inputs
   ------
   el           (1,6)  Reference orbital elements [a,i,W,w,e,M]
   g             (.)   Geometric goals data structure
   nu            (1)   Time step for the simulation [sec]

   -------
   Outputs
   -------
   xH           (6,1)  Relative position and velocity in Hills frame [km; km/s]
