title: Why JSON.stringify($('#calendar').fullcalendar('clientEvents')) fails?
body: <p>As title, when I try to do:</p>
  
  <pre><code>myString = JSON.stringify($('#calendar').fullcalendar('clientEvents'));
  </code></pre>
  
  <p>it fails. I tried to alert <code>myString</code> but I see a series of <code>[Object object], ... .</code> But if i try to alert <code>myArray[0].title</code> for example, it returns correctly.</p>
  
  <p>Where I'm doing wrong?</p>
  
  <p>P.S. The goal is to obtain a string to save on a file via AJAX.</p>
