	Improved Behaviour from http://www.advantax.org/scripts/behaviour.js 
   Behaviour v1.1 by Ben Nolan, June 2005.

   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).

   Version 1.2:
   Anthon Pang:
   - [enh] Add parentNode parameter to getElementsBySelector().
   - [enh] getElementsBySelector() is now a wrapper for Dean Edwards' cssQuery.
   - [enh] Add applyTo(element, selector).
   James Estes:
   - [fix] Declare local variables as 'var'
