Elixir Style Guide

Forced consistency.

If some view the code in 4 space mode, and some view it in 2 space mode ---- the style of how they implement stuff will diverge. Those using 2 spaces will be more comfortable with more levels of indent than those using the 4 spaces. Perhaps, or worse.

Also, like 1 less (strange) character in the code seems ... cleaner. I don't know, it's an emotional thing, but I wanted to share the emotional thing.
