Collections is cool but Plex auto-creates them, even when where is only one movie in a collection.
You can turn this off, but when you have to create *all* collections by hand.. I figured I'd leave it on and then
just prune the extra collections once in a while.. at least that was the thought for this script (picked up most of
it from a Reddit thread).

            movie.removeCollection(collection)
