formatting & docs changes

Ran this through `./ios/docs/install_docs.sh` to double-check things.

 * Less-specific initializers above more-specific per Apple convention.
 * Shores up `accessToken` docs as property, not a method.
 * Edited comments for consistency and/or to keep them out of the docs.
