* Enhances {ComplexTableField} with the ability to list groups and given members.
* It is based around groups, so it deletes Members from a Group rather than from the entire system.
*
* In contrast to the original implementation, the URL-parameters "ParentClass" and "ParentID" are used
* to specify "Group" (hardcoded) and the GroupID-relation.
*
* @todo write a better description about what this field does.
*
* Returns either:
* - provided members
* - members of a provided group
* - all members
* - members based on a search-query
*
* @package cms
