 * Method annotation used for methods that should be invoked once the page is fully loaded. This is useful for one-time
 * component initializations that can't be done at instance initialization time, such as references to embedded
 * components or blocks.
 * 
 * PageLoaded methods should take no parameters and return void. They must either have this annotation, or be named
 * "pageLoaded".
