+The keys in NSUserDefaults are the same name as your properties. If you'd like to prefix or alter them, add a `transformKey:` method to your category. For example, to turn "userName" into "NSUserDefaultUserName":

 Registering defaults is done as usual, on NSUserDefaults directly (use the same prefix, if any!).
