 * Function:    dump_extlink
 *
 * made by: PVN
 *
 * Purpose:     Dump an external link
 *  Since external links are soft links, they are dumped on a trial error
 *   basis, attempting to dump as a dataset, as a group and as a named datatype
 *   Error messages are supressed
 *
 * Modifications:
 *      Neil Fortner
 *      13 October 2008
 *      Function basically rewritten.  No longer directly opens the target file,
 *      now initializes a new set of tables for the external file.  No longer
 *      dumps on a trial and error basis, but errors are still suppressed.
