- Track theater in ControlPoint.
Simplifies finding the owning theater of a control point. Not used yet.
- Clean some cruft out of FlightPlanBuilder.
- Clean up silly some exception handling.
- Move FlightPlan instantiation into the builder.
I'm working on moving the builder to be owned by the Flight, which will simplify callers that need to create (or recreate) flight plans for a flight.
- Simplify IBuilder constructor.
We have access to the theater via the flight's departure airbase now.
- Move FlightPlan creation into Flight.
For now this is just a callsite cleanup. Later, this will make it easier
to separate unscheduled and scheduled flights into different classes without complicating the layout/scheduling.
- Remove superfluous constructors.
- Remove unused Package field.
Split the oversized file into one per plan type. This also moves the
layout responsibility out of the oversized FlightPlanBuilder and into
each flight plan type file.
