allow a class to override the display of individual fields; since this

is at the class level, it can look at other fields
(ie. z_num_hdr_fields) for lengths or other parameters that modify the
display.

implemented for z_hdr_fields, z_other_fields.  probably useful for
  selecting z_sender_sockaddr values too.
