//======================= Script:   /js/class_external js ()===========================
/* This is an ajax import pseudo-class for javascript for including wikis, essays, or
 * in the future other external pages into a THL page. 
 * The dependencies are:
 *
 * 1. Links should have #wiki= or #essay= prepended to the public url path from the collab site
 * that leads to the targeted wiki. In other words, an "a" element might look like this:
 *
 * <a href="#wiki=/access/wiki/site/71015a3a-5b85-424d-8056-8c5d527dd584/business%20hours.html">Text</a>
 *
 * 2. The various reader scripts, such as wiki_reader.php. Its relative location is set in the wiki_reader_url variable, etc. below.
 *
 * Aside from these two you can drop this whole file into a document as a linked script and
 * it should work. If it doesn't, you may need to check that PHP is allowed to read remote urls.
 *
 * This is based on the object created by Jed (jev3a@virginia.edu) and generaliczed by Than (ndg8f@virginia.edu)
 *
