	/**
	 * 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 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.
