   Behaviour v1.1 by Ben Nolan, June 2005. Based largely on the work
   of Simon Willison (see comments by Simon below).

   Description:
   	
   	Uses css selectors to apply javascript behaviours to enable
   	unobtrusive javascript in html documents.
   	
   Usage:   
   
	var myrules = {
		'b.someclass' : function(element){
			element.onclick = function(){
				alert(this.innerHTML);
			}
		},
		'#someid u' : function(element){
			element.onmouseover = function(){
				this.innerHTML = "BLAH!";
			}
		}
	};
	
	Behaviour.register(myrules);
	
	// Call Behaviour.apply() to re-apply the rules (if you
	// update the dom, etc).

   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
