FS::state - Object methods for state/province records
=head1 SYNOPSIS
use FS::state;
$record = new FS::state \%hash;
$record = new FS::state { 'column' => 'value' };
$error = $record->insert;
$error = $new_record->replace($old_record);
$error = $record->delete;
$error = $record->check;
=head1 DESCRIPTION
An FS::state object represents a state, province, or other top-level
subdivision of a sovereign nation. FS::state inherits from FS::Record.
The following fields are currently supported:

=item statenum
primary key
=item country
two-letter country code
=item state
state code/abbreviation/name (as used in cust_location.state)
=item fips

=back
