title: How to override Backbone.sync?
body: <p>I'm trying out Backbone.js, and one of the things I'm trying is to make a call to a remote API, so I need to be able to override Backbone.sync, as I understand <a href="http://backbonejs.org/#Sync" rel="noreferrer">the documentation</a>.</p>
  
  <p>There isn't an example of how to do that in the documentation itself, and there doesn't appear to be a google group for Backbone... can someone point out an example for doing this? </p>
