  Comments: Declaration of the CNetObjEnumerator COM object. This COM object
            is used to get an enumeration for the members in a container and
            their properties. If user simply needs all the objects in a given
            container then they can use the GetContainerEnum method. If user
            wants to perform some advanced searches/queries then they should
            use the set of three functions (SetQuery, SetColumns, Execute) to
            Setup and execute a query against the container. Both sets of methods
            return IEnumVaraint supporting objects. This object will allow user
            to go through all the values returned by queries.
