/** provides a default implementation of a <type>XSortableGridData</type>.

    <p>This service must be created with a secondary grid data model, which all actual data requests are delegated to.
    But before providing this data to the service's own clients, it is sorted, according to the sort order defined
    via the <code>XSortableGridData</code> interface.</p>

    <p>The service implementation is able to compare the default scalar types, plus strings.</p>

    <p>For determining the data type of a column which the data should be sorted by, the first non-<VOID/> data encountered
    in this column is taken into account. Further read requests to this column will assume that all non-<VOID/> data is of
    the same type.</p>

    <p>Consequently, you cannot use this service with data sets containing heterogenous data in a given column.</p>

    <p>All requests made via the <type>XMutableGridDataModel</type> are delegated to the <code>XMutableGridDataModel</code>
    instance passed in the service constructor.</p>

    <p>Note that changing the data might result in the sort order being destroyed. If you want to ensure
    that the data represented by the model is still sorted after your modifications, you should call
    <member>XSortableGridData::sortByColumn</member>, again.</p>
