/**
 * Register a user settings page with the admin panel.
 * This function extends the view "usersettings/main" with the provided view. This view should provide a description
 * and either a control or a link to.
 *
 * Usage:
 * 	- To add a control to the main admin panel then extend usersettings/main
 *  - To add a control to a new page create a page which renders a view usersettings/subpage (where subpage is your new page -
 *    nb. some pages already exist that you can extend), extend the main view to point to it, and add controls to your
 * 	  new view.
 *
 * At the moment this is essentially a wrapper around elgg_extend_view().
 *
 * @param string $new_settings_view The view associated with the control you're adding
 * @param string $view The view to extend, by default this is 'usersettings/main'.
 * @param int $priority Optional priority to govern the appearance in the list.
