Alternative to routerState.parent which no longer exists in angular2
<p>In angular2 rc5, I had this code.</p>

<pre><code>this.router.routerState.parent(this.route).params.forEach((params: Params) =&gt; {
    url = params['url'];
    id = +params['id'];
});
</code></pre>

<p>I had to use this because I was two levels down on my router, and for some reason doing this didn't work.</p>

<pre><code>this.route.params.forEach((params: Params) =&gt; {
        url = params['url'];
        id = +params['id'];
    });
</code></pre>

<p>I am still happy to do this, but in angular2 the <code>.parent</code> method no longer exists on routerState.</p>

<p>Can I achieve what I want, but using a different method that is available in angular 2.0.0?</p>
