Added a new command to convert graphics_objects into nodes and elements. The command allows the choice of creating linear_tensor_product elements or clouds of nodes on surfaces.  When creating clouds of nodes the data field is used to control the node density. Added a new macro to the enumerator macros that automatically makes an appropriate Option_table entry for selecting from that enumerator. Removed old surface_data code which only worked for iso_surfaces
