class views_handler_field_content in Content Construction Kit (CCK) 6

The subclass adds basic field and formatter info, for field-specific subclasses to use if they need to.

Fields could extend this class if they want field and formatter handling but don't want the multiple value grouping options created by views_handler_field_content_multiple.
