 * Do the report generation.
 *
 * A problem: I really need multiple cursors.  I'd rather not look into
 * the depths of the current symbol table implimentation (there are the
 * cursors there that I could use) so that a different (faster!) symbol
 * table can be used in the future.
 *
 * I could get a key (tag), get it's sub-keys (TCIDs), then get the key
 * again to reset to the top level, _then_ get the next key.  That would
 * be very inefficient.
 *
 * The solution I chose is to extract all tags into a list (char array),
 * then go thru that list with the cursor free for other levels to use.
 *
 *  (1) make a list (2d char array) of all Tags
 *  (2) search for the first tag that has a "stime" record, and use that as
 *      the date (MMDDYY) that the tests were run.
 *  (3) print the report header
 *  (4) go thru all tags and report each as described at the beginning of
 *      this file
