title: angular ng-route : undefined route nesting
body: <p>I want to route to all child paths to m.</p>
  
  <pre><code>.state('index.m', {
          url: "m",
          views: {
              "viewContainer": {
                  templateUrl: "p/m.html"
              }
          }
      })
  </code></pre>
  
  <p>Thus /m and /m/123  and /m/123/a all map to the same route <code>index.m</code>  </p>
