title: Create breadcrumb when navigating nested components (Angular 2)
body: <p>I am struggling with this :)</p>
  
  <p>The idea is to have a  component and when navigate trough sub-views update the breadcrumb for example:</p>
  
  <pre><code>&lt;breadcrumb&gt; Products / Category-C / My-Product &lt;/breadcrumb&gt;
  
  Products -&gt; Category-A
           -&gt; Category-B
           -&gt; Category-C  
                    |-&gt; My-Product
  </code></pre>
