title: Two-way binding with $routeParams?
body: <p>When using <code>ng-view</code> and <code>$routeProvider</code>, it's possible to inject <code>$routeParams</code> to get values of the path, like <code>/foo/:id/:user/:item</code>. Is there any way to set those parameters in the path? Something like <code>$routeParams.id = 3</code>, and then have that reflected in the url.</p>
  
  <p>I know this effect could be achieved through <code>$location.path()</code>, but I'm hoping to for a higher level of abstraction that doesn't require string manipulation.</p>
