/**
   * Adds hover support to IE6 browsers
   * 
   * This jQuery plugin will parse the stylesheets
   * for any :hover rules and append them using Javascript
   * while creating a ne rule in the stylesheet with a .hover class
   *
   * Initilaize using:
   *  
   * $(document).ready(function(){
   *	  $.ie6CSSHover();
   * });
   *
   * Limitations:
   * This script is not meant to parse :hover pseudo classes
   * that contain :hover within a selector:
   *
   * Example:
   * div span:hover p{font-size:12px} // WILL NOT WORK
   * div span p:hover{font-size:12px} // WILL WORK
   *
