Initial version of the bone wrapper is complete.
Created an interface class for 3D transform methods on a 3D object.
Final changes to the bone wrapper, for now.
Added files for a skeleton class wrapper.  Unfortunately this can't be completed until we have a more solid solution for the resource system because of Ogre's design.
Updated the Graphics::Mesh wrapper slightly in preparation for writing all the graphics wrappers, which will have to wait.
Somehow I forgot to put virtual in my virtual methods.
API updates from the Graphics::Mesh class.
