/* BEHAVIOURS \\\
**************************************************

// The format of the rule definitions is like so:
BASIC BEHAVIOUR 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);


// To add an onclick event to every list item <li>
// in a page - you would write something like this:

var myRules = {
	'li' : function(element){
		element.onclick = function(){
			// Your onclick event goes here - eg;
			// load a page - do an AJAX etc.;
		}
	}
};
Behaviour.register(myRules);
