=== next steps ===
    - add tests for 3d orbital elements in local frame
    - maneuvering
        - still need to render the spacecraft orbits
        - display orbital elements in UI
        - add more testing to maneuvers
            - not updating simulation, add checks along orbital path
            - verify orbital elements change as expected
    - only then look at interplanetary transfers


=== Project Documentation ===
    - remember to periodically check the reference docs against new changes

=== Simulation/Physics ===
    - actually, we should start out simpler. create and test maneuvers in planetary
        frame before starting on interplanetary patched conics, oops
        - will still need hohmann transfers, circularizing, plane change, etc.
    - IMPORTANT: for the graphical sim, we're calculating 100 physics steps per
        frame. we need to test, and make a compromise on performance vs sim
        accuracy, and have this set as a config constant, MAX_STEP_SIZE, with
        a good discription nearby in the code.
        - could also try an alternative step method with error function
            eg) https://en.wikipedia.org/wiki/Runge%E2%80%93Kutta%E2%80%93Fehlberg_method
    - remove bodies on non closed orbits after they are a certain distance from
        the root body, or bary-center

=== Simulation Config Files ===
    - a format with nested children would be nice

=== rendering ===
    - change zoom speed based on camera distance
    - initial zoom seems off
    - refactor render_state folling conditionals, should now explicitly requre
        a target body/craft always
    - 3d object for spacecraft?
