 * NAME:        SHOP_Data.h ( SHOP Library, C++)
 *
 * COMMENTS:    This class is used for passing data between the SHOP library
 *              and the IFD library.  Because the data passed to renderers can
 *              be arbitrary, we need a nice clean mechanism which doesn't
 *              encourage memory leaks.
 *
 *              This class is meant to be sub-classed.
