*
* @description
*
* A Sidenav component that can be opened and closed programatically.

* By default, upon opening it will slide out on top of the main content area.
*
* For keyboard and screen reader accessibility, focus is sent to the sidenav wrapper by default.
* It can be overridden with the `md-sidenav-focus` directive on the child element you want focused.

* Open Left Menu

* @param {expression=} md-is-open A model bound to whether the sidenav is opened.
* @param {string=} md-component-id componentId to use with $mdSidenav service.
* @param {expression=} md-is-locked-open When this expression evalutes to true,
* the sidenav 'locks open': it falls into the content's flow instead
* of appearing over it. This overrides the `is-open` attribute.
*
* The $mdMedia() service is exposed to the is-locked-open attribute, which
* can be given a media query or one of the `sm`, `gt-sm`, `md`, `gt-md`, `lg` or `gt-lg` presets.
* Examples:
*
* - ``
* - ``
* - `` (locks open on small screens)
