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());
});
