title: defines manually routes using Symfony2
body: <p>I've set up my entities, now I want to 
  use the doctrine:generate:crud, during this command it asks what route 
  prefix I would like. I would expect that this means that the routes 
  would automatically be generate, this is not happening. So I need to 
  know if it is supposed to generate the routes, or if I'm supposed to 
  create them all manually? If it is the case that I need to generate 
  them manually is there a route class, to define all the routes for the 
  CRUD operations? </p>
