title: How to tell if tinyMCE has been initated?
body: <p>I initiate the tinyMCE like this in multiple tabs of JQuery:Tab. But I find to init tinyMCE multiple times yields readonly text areas. Thus I wish to check if tinyMCE is already initated. Is there a method like isInitated() or something similarly convenient there? </p>
  
  <pre><code>tinyMCE.init({
      mode : "textareas",
      theme : "simple",
      width : "500",
      height : "300"
  });
  </code></pre>
