docs: Decorator utility to collect flask routes in a dictionary.
  
      This function together with :func:`add_routes` provides an
      easy way to split flask routes declaration in multiple modules.
  
      :param gatherer: dict in which will be collected routes
  
      The decorator provided by this function should be used as the
      `original flask decorator <http://flask.pocoo.org/docs/latest/api/#flask.Flask.route>`_
      example::
  
         routes = []
         route = routes_collector(routes)
  
         @route('/volumes/', methods=['GET', 'POST'])
         def volumes():
             return 'page body'
  
      After you've collected your routes you can use :func:`add_routes` to register
      them onto the main blueprint/flask_app.
