  * TODO:
+ * - impulsive orbital maneuvers
+ * - Hohmman transfer orbits
+ * - make an 'overlay' graphic for things like apoapsis, perisapsis, f1, f2,
+ *   	flight path
+ * - patched conic method for transferring between 2 grav bodies
  * - organize orbit functions into interface/internal functions
  * - add an 'orbits' namespace
  *   - drop orbit from interface functions,
  *   	eg) 'orbitGetTimeOfFlight()' becomes 'getTimeOfFlight()'
