Subject: [PATCH] Changed key from Math.random() to todo.cid
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

It doesn’t make much sense to generate a random key for each todo render, because it will re-draw all todo’s DOM nodes on each model change. I changed it to the unique identifier ``todo.cid`` already supplied by the backbone model.
