    Customizable report stub to do the following:
 o  Select a person with all ancestors and all descendents.
 o  Add to selection all other persons within a user-specified number of
       links from any person in the first selection.
 o  Turn the selected set of persons into a list
 o  Call a report subprogram to process the list.
