// Forward declarations
// This file is included, directly or indirectly, almost everywhere in
// FlightGear, so if any of its dependencies changes, most of the sim
// has to be recompiled. Using these forward declarations helps us to
// avoid including a lot of header files (and thus, a lot of
// dependencies). Since Most of the methods simply set or return
// pointers, we don't need to know anything about the class details
// anyway.
