Merge pull request #10 from volivarez60/main

updated gltf importer with preliminary mesh import support. meshes in nearly all encodings appear to import cleanly, but there is some issue remaining. meshes converted to bots display correctly in wireframe and opengl in mged/archer, but do not raytrace correctly. possibly implies some issue in the bot data structure setup, but this is significant progress regardless, and sets the stage for creating a proper gcv plugin.
