      # @resource_actions is used to customize the actions which appear under
      # each item on the tables. This is really a nice feature because allows
      # us to enable actions for items without much effort. For example adding
      # a "Recover from Trash" action:
      #
      #     def index
      #       add_resource_action('Recover', {:action => 'untrash'}, {:confirm => Typus::I18n.t("Recover %{resource}?", :resource => @resource.model_name.human)})
      #       super
      #     end
      #
      # Additionally you can set a condition to each action passing a Proc as 4th parameter. If the proc return true
      # the item will be showed and if return false will be hidden.
      #
      #     def index
      #       add_resource_action('Recover', {:action => 'untrash'}, {}, Proc.new {|item| item.is_trash? })
      #       super
      #     end
      #

      # @resources_actions is used to build a list of custom actions which will
      # be appended beside "<h2></h2>" all the actions.
      #
      # Let's say for example that I want to be able to run the application
      # without sidebars and headers (headless mode). In this case I need to
      # somehow add custom actions to the page so I can navigate.
      #
      # Instead of having this code here, maybe it's better to duplicate the
      # actions on the pages. So for example: Admin::PostsController#index will
      # show a link to add new in the sidebar and beside the "<h2>" header.
