 * 
 * This scripts functions by finding the <div id="BlueZoneLaunchTag" > tag and parsing 
 * its contents to extract the <object> tag wrapped in an HTML comment tag. It then 
 * replaces the contents of the <div> with the uncommented <object> tag.
 * This copied tag is not HTML interpreted by the browser, but a new tag inserted 
 * by JavaScript. For whatever reason, this satisfies the frivolous IP patent lawsuit 
 * brought by Eolas against Microsoft. http://en.wikipedia.org/wiki/Eolas
 *
 * This fix only needs to be implemented for MS IE 6+. However, as this file is intended 
 * for use only by the BlueZone system, which checks the browser type by another method 
 * there is no browser type check needed or included in this script.
