Summary: * Fixes #3 * Ordering: atomicity, then [optional] readonly, then value semantics (retain/copy/assign) * Removed redundant `readwrite` * No spaces between "getter = name" ("getter=name" instead) * Property method overrides renamed as well * self.isBlah, while technically not entirely correct, still resolves to [self blah], so left alone (@kimon had advice on this sort of naming issue last summer), and largely inconsequential Test Plan: * Compile and run
