/** BEGIN getElementsBySelector CODE ******************************************/

/* document.getElementsBySelector(selector)
   - returns an array of element objects from the current document
     matching the CSS selector. Selectors can contain element names, 
     class names and ids and can be nested. For example:
     
       elements = document.getElementsBySelect('div#main p a.external')
     
     Will return an array of all 'a' elements with 'external' in their 
     class attribute that are contained inside 'p' elements that are 
     contained inside the 'div' element which has id="main"

   New in version 0.4: Support for CSS2 and CSS3 attribute selectors:
   See http://www.w3.org/TR/css3-selectors/#attribute-selectors

   Version 0.4 - Simon Willison, March 25th 2003
   -- Works in Phoenix 0.5, Mozilla 1.3, Opera 7, Internet Explorer 6, Internet Explorer 5 on Windows
   -- Opera 7 fails
