=head1 SYNOPSYS

    # Connect
    my $dbi = DBIx::Custom::MySQL->connect(user      => 'taro', 
                                           password => 'kliej&@K',
                                           database  => 'your_database');
    
    # Last insert id
    my $id = $dbi->last_insert_id;

=head1 ATTRIBUTES

You can use all attributes of L<DBIx::Custom>

=head2 C<database>

Database name

    $dbi      = $dbi->database('your_database');
    $database = $dbi->database;

=head2 C<host>
