title: Angular 2 Scroll to top on Route Change
body: <p>In my Angular 2 app when I scroll down a page and click the link at the bottom of the page, it does change the route and takes me to the next page but it doesn't scroll to the top of the page. As a result, if the first page is lengthy and 2nd page has few contents, it gives an impression that the 2nd page lacks the contents. Since the contents are visible only if a user scrolls to the top of the page.</p>
  <p>I can scroll the window to the top of the page in ngInit of the component but, is there any better solution that can automatically handle all routes in my app?</p>
