    use Validation::Class::Simple;

    my $rules = Validation::Class::Simple->new(
        fields => {
            address_state => {
                state => 1
            }
        }
    );

    # set parameters to be validated
    $rules->params->add($parameters);

        # handle the failures
    }

=head1 DESCRIPTION

Validation::Class::Directive::State is a core validation class field directive
that handles state validation for states in the USA. States will be validated
against a list of state (case-insensitive abbreviated and long) names.

For example: ny, NY, New York, and new york will validate.
