/*   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).
