  # This is the method that renders most of the the public content. It recieves
  # a :locale and a :page_path parameter through the params hash. It looks up
  # the node with the corresponding unique_name attribute. The method doesn't
  # return a node though, the node is really a proxy object for pages. It
  # returns the most recent page associated to this node instead.
