Get only new items from Firebase

	// assumes you add a timestamp field to each record (see Firebase.ServerValue.TIMESTAMP)
	// pros: fast and done server-side (less bandwidth, faster response), simple
	// cons: a few bytes on each record for the timestamp
	var ref = new Firebase(...);
	ref.orderByChild('timestamp').startAt(Date.now()).on('child_added', function(snapshot) {
	console.log('new record', snap.key());
	});
