title: Material-ui App Bar w/ react-router
body: <p>I'm wondering how is the proper way to add router links to the material-ui AppBar demo.</p>

  <p>I'm new to react and my first guess was to do the navigation programmaticaly (in the click handler for example) but it seems that it isn't the way react-router works.</p>
  
  <p>Regards</p>
