Requires [Dean Edwards CSSQuery](http://dean.edwards.name/my/cssQuery/ "CSSQuery").

Usage
------

		Behavior.register(
			"b.someclass",
			function(element) {
				element.onclick = function(){
					alert(this.innerHTML);
				}
			}
		);

		Behavior.register(
			"#someid u",
			function(element) {
				element.onmouseover = function(){
					this.innerHTML = "BLAH!";
				}
			},
			getElementByID("parent")
		);

Call `Behavior.apply()` to re-apply the rules (if you update the dom, etc).
