// URL hash should be the keeper of its own state. In this example we're using the "comparing" state,
// i.e. are we in compare mode or not. Since the toggle button lives in the sidebar, we would do something
// like this in the sidebar component:

getInitialState() {
  comparing: false
}

componentWillMount() {
  this.updateHash = hashed.register({comparing: false}, this.onHashChange);
