title: Reveal Modal with cookie to display only once
body: <p>I'm using the (<a href="http://www.zurb.com/playground/reveal-modal-plugin" rel="noreferrer" title="Reveal Modal">Reveal Modal</a>) and loading it on page by using this code:</p>
  
  <pre><code>$(document).ready(function() {
      $('#myModal').reveal();
  });
  </code></pre>
  
  <p>How can I modify this, I believe using cookies (is there another way?), so that it will only pop one time for a user over the course of lets say 1 week?</p>
