      Description:
          Stubs out a active_scaffolded controller. Pass the model name,
          either CamelCased or under_scored.
          The controller name is retrieved as a pluralized version of the model
          name.

          To create a controller within a module, specify the model name as a
          path like 'parent_module/controller_name'.

          This generates a controller class in app/controllers and invokes helper,
          template engine and test framework generators.

      Example:
          `rails generate active_scaffold:controller CreditCard`

          Credit card controller with URLs like /credit_card/debit.
              Controller:      app/controllers/credit_cards_controller.rb
              Functional Test: test/functional/credit_cards_controller_test.rb
              Helper:          app/helpers/credit_cards_helper.rb

        template 'helper.rb', File.join('app/helpers', class_path, "#{controller_file_name}_helper.rb")
      end
