Cache the parsed navigation and airport data in a binary file to reduce startup times and memory consumption (since only referenced FGPositioned elements are held in memory). Data will be reimported when the mod-time of any input file is changed. If a global file is changed (nav.dat, awy.dat, apt.dat, etc), the cache will be completely rebuilt, which takes approximately 30 seconds on moderate hardware. (Future work may reduce this).
