function disableLayoutDirective() {
    // Return a 1x-only, first-match attribute directive
    config.enabled = false;

    return {
      restrict : 'A',
      priority : '900'
    };
  }
Special directive that will disable ALL Layout conversions of layout
attribute(s) to classname(s).

<link rel="stylesheet" href="angular-material.min.css">
<link rel="stylesheet" href="angular-material.layout.css">

<body md-layout-css>
 ...
</body>

Note: Using md-layout-css directive requires the developer to load the Material
Layout Attribute stylesheet (which only uses attribute selectors):

      `angular-material.layout.css`

Another option is to use the LayoutProvider to configure and disable the attribute
conversions; this would obviate the use of the `md-layout-css` directive
