	 * other places where they accessed/used/saved.
	 *
	 * The safest way to add new fields is to add them to the dropdown and the

	 * `extra fields` which are saved in the post meta and will be properly
	 * handled by the admin Feedback view and the CSV Export without any extra
	 * work.
	 *
	 * If there is need to add a field to the allowed fields, then please
	 * take proper care to add logic to handle the field in the following places:
	 *
	 *  - Below in the switch statement - so the field is recognized as allowed.
	 *
	 *  - Grunion_Contact_Form::process_submission - validation and logic.
	 *
	 *  - Grunion_Contact_Form::process_submission - add the field as an additional
	 *      field in the `post_content` when saving the feedback content.
	 *
	 *  - Grunion_Contact_Form_Plugin::parse_fields_from_content - add mapping
	 *      for the field, defined in the above method.
	 *
	 *  - Grunion_Contact_Form_Plugin::map_parsed_field_contents_of_post_to_field_names -
	 *      add mapping of the field for the CSV Export. Otherwise it will be missing
	 *      from the exported data.
	 *
	 *  - admin.php / grunion_manage_post_columns - add the field to the render logic.
