   ------
   Inputs
   ------
   e                (1)   Eccentricity
   nu               (1)   True anomaly [rad]
   g                (.)   Data structure of geometric goals
   n                (1)   Mean orbit rate [rad/s] (optional)
                           * time-derivatives returned if provided
                           * nu-derivatives returned if NOT provided

   -------
   Outputs
   -------
   xH              (6,1)  Hills frame state at nu (time-domain)
   D               (6,1)  Integration constants for trajectory
   dH               (1)   Integration constant found by setting H = 0 at nu
