title: Zend Framework 2 - Add style to controller
body: <p>I have been looking through the documentation, and I can't seem to find a way to do this. I know I can use headScript to add style sheets to individual views, but I would like to add a style sheet to all actions in a controller.</p>
  
  <p>Has anyone done this? I am sure it is a simple task.</p>
  
  <p>Thanks</p>
