This script will insert an entry into the Chado organism table. The combination genus and species is
required to be unique. If either of those items are not provided, or if that combination is already in
the database, the script will exit without doing anything. Technically, those are the only two things
required, but it is strongly suggested that you provide a common_name and abbreviation.
The --name_only option is intended for use primarily at install time, to check the database for the
existence of an entry in the organism table with a given common_name. If it is present, it prints "1"
and exits, otherwise it prints "0" and exits. The options --common_name must be used in conjunction with
--name_only.
