title: Create a last visited list with Symfony & Twig
body: <p>I want to create a “last visited pages” list with Symfony and Twig.</p>
  
  <p>For that purpose I wrote a history service which saves the last visited routes in the session.</p>
  
  <p>But I just have the route name no alias for the user experience.</p>
  
  <p>So the route <code>country_info</code> should hold a string like “Country Information”.
  Is it possible to define a alias in the <code>routing.yml</code>?</p>
