Turtle initial commit

The code is a mess - I am going to do a complete rewrite of it, but I would appreciate you poking the Turtle Methods as they stand.

Recipe is currently a journal+turtle, I may change this to an atomic manipulator along with a new custom texture once I have the code where I want it to be.

There are some other things I'd like to do - but they're a secret for now until I do them :)
