title: How to add Tangle.js as an external resource to jsfiddle
body: <p>trying to add Tangle.js library to jsfiddle and it's not working.</p>
  
  <p>Fiddle is <a href="https://jsfiddle.net/pL0bbkcr/" rel="nofollow">here</a></p>
  
  <p>Code is:</p>
  
  <pre><code>   var tangle = new Tangle (document.getElementById("bedroomcostcalculator"), {
      initialize: function () {
          this.bedrooms = 2;
          this.cost = 300000;
          this.costperbedroom = 150000;
          },
  update: function () {
          this.cost = this.bedrooms * this.costperbedroom;
         }
  });
  </code></pre>
  
  <p>URL for Tangle is: <a href="http://worrydream.com/Tangle/Tangle.js" rel="nofollow">http://worrydream.com/Tangle/Tangle.js</a></p>
  
  <p>We've added the URL to External Resources, but it's not picking it up. I've seen other posts about needing to link to CDN format - how would we do that?</p>
