//  Thank you http://www.quirksmode.org/ for the

//  No thanks to Eolas for their embed patent...
//
//  ----------------------------------------------
//  Accepts
//  ----------------------------------------------
//  URL: html for flash object embeding. The file is XHTML formatted.
//  ID : id of div to replace with html from URL
//  MIN: minimum version of flash which must be installed
//  CUR: current high version of flash (required because IE is dumb) 
//
//  ----------------------------------------------
//  Example Usage
//  ----------------------------------------------
//  <div id="flashcontainer">
//		This is where the NON-Flash version goes.
//  </div>
//  ...
//  <SCRIPT type="text/javascript">
//      //<![CDATA[
