module Responders
module ControllerMethod
# Adds the given responders to the current controller's responder, allowing you to cherry-pick
# which responders you want per controller.
#
# class InvitationsController < ApplicationController
# responders :flash, :http_cache
# end
#
# Takes symbols and strings and translates them to VariableResponder (eg. :flash becomes FlashResponder).
# Also allows passing in the responders modules in directly, so you could do:
#
# responders FlashResponder, HttpCacheResponder
#
# Or a mix of both methods:
#
# responders :flash, MyCustomResponder
#
