+   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).
