      # The example below resembles 'vim' (the popular terminal-based text
      # editor):

      # @example
      #   Vedeu.group 'title_screen' do
      #     add 'welcome_interface'
      #     # ...
      #
      #   Vedeu.group 'main_screen' do
      #     add 'editor_interface'
      #     add 'status_interface'
      #     add 'command_interface'
      #     # ...
      #
      # @note
      #   Creating a group with the same name as an existing group overwrites
      #   the existing group.
      #
      # @param name [String] The name of this group.
