title: is there a way to load an external javascript file inside the tinymce iframe?
body: <p>Is there a simple way to load external javascript that will work inside of a TinyMCE iframe?</p>
  
  <p>The only thing I've found (that might be the answer) is this: <a href="http://www.tinymce.com/wiki.php/API3:class.tinymce.dom.ScriptLoader" rel="noreferrer">http://www.tinymce.com/wiki.php/API3:class.tinymce.dom.ScriptLoader</a></p>
  
  <p>But I'm not sure how to load this properly or if it works at all.  I tried to load it before and after the <code>tinymce.init</code> directive, even inside it, but nothing seems to work.  Just wondering how to intiailize the "ScriptLoader" function.</p>
