title: Symfony 2.0.3 Global template variable
body: <p>I've got an Entity that I want to associate with the users session.
  I created a service so that I could reach this info from where ever.</p>
  
  <p>in the service i save the entities id in an session variable
  and in the <code>getEntity()</code> method i get the session variable and with doctrine find the entity and return it.</p>
  
  <p>this way to the template i should be able to call <code>{{ myservice.myentity.myproperty }}</code></p>
  
  <p>The problem is that myservice is used all over the place, and I don't want to have to get it in every since Action and append it to the view array.</p>
  
  <p>Is there a way to make a service accessible from all views like the session <code>{{ app.session }}</code> ?</p>
