Pika - Preferred Grouping Author (Cataloging)

The Preferred Grouping Author will replace every instance of the Source Grouping Author for any grouped work with that Grouping Author, not just for a single grouped work of interest. This is for legitimate variations on an author where records will have one form of the author and some with another form of the author.  Both forms of the author are right and there is not a normalization or cataloging problem.  In that case, there is more than one way to catalog a work, so the Preferred Grouping Author form is used to add entries into a table when a normalized author will now display with a preferred author.
