Path: Orbit/OrbitManeuver

% Lower orbits starting from a hyperbolic orbit
 This routine will change orbits. The first is for insertion into the
 planetary orbit from a hyperbola. The second and additional to lower
 apoapsis. All maneuvers happen at periapsis. All are in-plane maneuvers.
 You need at least one orbit. d.maneuver is compute during initialization.

 Type OrbitLoweringManeuvers for a demo of lunar insertion.
