This will allow us to perform access control validation in SimGear. The current implementation of SGPath::validate() is 99% Rebecca Palmer's work (see fgValidatePath() in FlightGear commit 6a30e7086ea2f1a060dd77dab6e7e8a15b43e82d); only the coding style has been slightly modernized here since we can now use, for instance, C++11's range-based for loop.
