title: Possible to add a vertical separator between Angular Material tabs?
body: <p>A client is requiring us to add a vertical line in between our angular material tabs.  While this appears to be frowned upon, we cannot figure out how to accomplish this.<br>
  Here is an example: 
  <a href="https://material.angularjs.org/latest/demo/tabs" rel="nofollow noreferrer">Angular Material tabs</a></p>
  
  <p>We've tried the angular md-divider but this only appears to work for vertical lists that need a horizontal line.  Any help is appreciated.</p>
