Titles

Seems like a reasonable page to have, but I kinda don't like how official it makes these titles and options sound. There are surely many more ways to layout your code, and I've certainly never heard anyone else use the terms "Spider Layout" or "Tower Layout". :-P Besides the combined layout, I'd say all these other styles are also modular (the adjective, not the title).

Also I think we should rename this page Robot Code Layout or something similar.
