      # Adds buttons "Next", "Previous", "Save" and "Finish" to form and adds hidden field with current step name.
      #
      # Add to locales for changing step names:
      #   en:
      #     stepper:
      #       next_step: 'Next step'
      #       previous_step: 'Previous step'
      #       save: 'Finish later'
      #       finish: 'Finish'
      #
      # +next_step+ button validates, saves current step and renders next step of form;
      # +previous_step+ saves current step and renders previous step of form;
      # +save+ save current step and redirects to index page;
      # +finish+ is showed only for last step instead of +next_step+ button and it validates, saves last step and redirects to show.
      #
      # If you want to have other partial for buttons than add partial to: +app/views/stepper/_fields.html.erb+
