"""This module contains some decorators that can be used to support
the page models. For example for an action that needs a page to be fully
loaded, the @require_loaded decorator will make sure the page is loaded
before the call is invoked.
This pattern is also useful for waiting for certain asynchronous events
to happen before executing certain actions."""
