title: Is it possible to implement group roles by SecurityBundle on Symfony2? (NOT FOSUser)
body: <p>One question please.</p>
  
  <p>I'm using the SecurityBundle of Symfony to manage roles. NOT FOSUserBundle!. It's possible to create and manage groups with this bundle?. In case NO, it's possible/easy migrate from SecurityBundle to FOSUserBundle?</p>
  
  <p>Thanks!</p>
