title: Pass variable in twig to included template
body: <p>I have set the rendering of an navigation menu en an separate twig template. Reason is the the menu is generated on two different places in the application. </p>
  
  <p>Now I want to give a parameter to the navigation menu so I know from with place it is generated are these some small differences. </p>
  
  <p>I tried the following code but the variable is not know in the navigation menu template:</p>
  
  <pre><code>{% set menuType = 'user' %}
  {% include 'MyBundle:nav.html.twig' with menuType %}
  </code></pre>
  
  <p>Also tried:</p>
  
  <pre><code>{% include 'MyBundle:nav.html.twig' with {'menuType': 'user'} %}
  </code></pre>
  
  <p>In both case twig generated the error that {{ menuType }} does not exists?</p>
