title: Change labels in slicknav when open/closed
body: <p>I'm trying to change the labels in Slicknav for when the Slicknav menu is opened and closed.</p>
  
  <p><a href="http://jsfiddle.net/913vm2mq/" rel="nofollow">In the jsfiddle, here.</a> I've used label closed for the default state, and for the open state another piece of text I would like another piece of text.</p>
  
  <p>Like this for the normal state:</p>
  
  <pre><code>$('#menu').slicknav({
      duplicate: false,
      label: 'label closed'
  });
  </code></pre>
  
  <p>I've tried using basic if this then that and I feel like I'm just messing up this very simple piece of javascript.</p>
  
  <p>Any help would be greatly appreciated!</p>
