Multi-Material Filament Loader

UPDATE: I have currently halted work on this project. I was able to get pretty good results, but after some thought, I'm not sure the large amount of waste generated from the extensive purging that is required for using only one hotend and the very long print times are worth it. It is a very cool idea and I may continue work on it at some point, but for now, I am letting it rest.
