The full route should be parsed correctly now.
Waypoints need to be uppercase, but let's be lenient on this.
Parse and store the arrival airport.
Handle departure airports correctly.
Note to self.
Also skip dots for now.
Make route item splitting a tiny bit more robust.
And simplify.
Some cleanup.
Refactorijg.
Even better, if insignificantly slower.
Got airway intersections working.
rsg->src and dstidt are both valid waypoints, so this is safe.
Note to self.
More notes.
