//
//  ucsdlib.autoRedirect
//
//  Purpose: To redirect Vignette articles to external web sites
//
//  Description: This function redirects a web page to, wait for it, another web
//  page. Automatically. It also checks to see if it is on preview-n or www-n.
//  No need to break that user experience while trying to be sneaky in Vignette.
//  On live web sites it will fetch and display the new page without breaking
//  the back button of the user's broswer. That's always a nice touch. Huzzah!
//
//  Usage: To use, add the following code to the source of your article's body.
//  Be sure to change the URL to the page you want to redirect to. Easy peezy.
//
//  <div>
//  <script src="http://orpheus.ucsd.edu/vignette_css/js/ucsdlib_autoRedirect.js" type="text/javascript"></script>
//  <script type="text/javascript">
//    ucsdlib.autoRedirect("http://www.example.com/dir/page.html");
//  </script>
