Altered ivars being accessed directly in init.

This is in response to Dave Delong's issue.

See here for definitive proof.

Fixes #6

I don't know if we should say init specifically because that leaves out other designated initializers like initWithFrame:. Maybe something like "initializer methods".

@jacobvanorder - Could you include that documentation link in the guide itself? Maybe just linking the "initializer methods and dealloc" text would work.

@jacobvanorder Thanks so much for the patch! 👍

@mattbischoff Thanks for opening up the style guide. I'll contribute more if I see anything else.

We've debated this internally recently, but lacked time to develop a formal proof. Great example of the benefit of opening up the guidelines to a wide audience.
