 * // Sync lookup for sidenav instance; this will resolve immediately.
 * $mdSidenav(componentId).then(function(instance) {
 *   $log.debug( componentId + "is now ready" );
 * });
 * // Async toggle the given sidenav;
 * // when instance is known ready and lazy lookup is not needed.

 * @param {expression=} md-is-locked-open When this expression evaluates to true,
 * the sidenav 'locks open': it falls into the content's flow instead

 * @param {string=} md-disable-scroll-target Selector, pointing to an element, whose scrolling will
 * be disabled when the sidenav is opened. By default this is the sidenav's direct parent.
