Arguments: outline item-value range
Called when an outline-item is being opened to return the list of subitems to display. The list of subitems currently stored on the outline-item is passed as the range argument. The default method simply returns this list, but methods could be added to return different ranges, which then become the subitems stored on the outline-item.
