Orbital Unity sandbox

The work here is very dated! The project has migrated to the private Epicycle repo. Sorry for the inconvenience! Build's will still be posted here on occasion.

• Refactor of OrbitalMechanics script
  • Broken into subclasses in anticipation of general variable method

• Fixed issue with maneuver nodes breaking while orbiting non-stationary bodies
• Fixed issue of maneuver nodes being placed inappropriately while on a hyperbolic trajectory
  • Note that this is about as imperfect as hyperbolic orbits generally are right now when approaching an asymptote
