Glitchey import

Just writing my first course for year 10 for the next unit (well actually as a revision of this unit and practice for me and have found that the library import creates a few ghost modules which need to be deleted. Even though the library does save a lot of time it does need to be double checked after import to ensure that the right stuff has been copied over. Also there's an issue that, unless you know your materials there's no way of knowing (except by feel) which resource will appear in each chapter. It's not a major glitch, just ensure you double check all resources when imported.
