 * ESJ - 2009/10/06                                                          *
 *                                                                           *
 * A handy little Javascript workaround for the annoying fact that the       *
 * XHTML 1.0 Strict DTD does not include the 'target' attribute, preventing  *
 * the use of the target="_blank" method of opening a link in a new          *
 * window. By including this .js file in a web page, all <a> tags marked     *
 * with rel="external" will open in a new window, just like they would       *
 * when the 'target' attribute was still legal.                              *
 *                                                                           *
 *  Example:                                                                 *
 *                                                                           *
 *       <a rel="external" href="http://www.earlisanhtmlgod.com">            *
 *                                                                           *
