 *
 * The function referred to here will output the HTML for the page that you want
 * to display. However if you want to hook into enqueue_scripts or styles you
 * should use the page-suffix that is returned from the function. (e.g.
 * `add_action("load-".$hook, hook_func);`)
 *
 * There is also another hook with the same name as the hook that's returned.
 * I don't remember in which order it is launched, but I believe the pertinent
 * code is in admin-header.php.
