body: <p>How do I programmatically retrieve content from a <code>WYSIHTML5</code> editor?
  Suppose the editor is instantiated as this:</p>
  
  <pre><code>var editor = new wysihtml5.Editor
  (
     $(this.el).find('textarea').get(0),
     {
        toolbar:      "toolbar",
        parserRules:  wysihtml5ParserRules
     }
  );
  </code></pre>
  
  <p>i would like to get the editor's content on <code>blur</code> event</p>
  
  <pre><code>editor.on
  (
     "blur",
     function()
     {
        //what here?
     }
  );
  </code></pre>
