Possible initial public release. After extensive testing, code amended to incorporate Laminar Research tools to build usable meshes for X-Plane, along with the correct files needed for the scenery. Normal maps also generating correctly. New class xp_scenery which performs generation of the mesh. Structure of files unified so that multiple tiles can be held in one single folder. Dependency for wand removed.
