- Change AIFlightPlan::waypoint into an independent class FGAIWaypoint
- Don't update leg count until the aircraft has passed the last waypoint that was created by the corresponding leg
- Clear ground network rendering for controllers that are no longer active.
* Added an AIAircraft that is shadowing the user aircraft's behavior, in terms of AI / ATC interactions
* Set up a shadow AI FlightPlan that is used for tracking the user's aircraft.
* Started transfering the ATC infrastructure to be driven by it's own subsystem
* Changed the bahavior of the "'" key so that it is no longer driven by ATCDCL, but it now triggered by the new subsystem based ATC module.
