I<Don't use this class directly!> Instead ask Mail::Field for new

=head1 SYNOPSIS

  use Mail::Field::AddrList;

  $to = Mail::Field->new('To');
  $from = Mail::Field->new('From', 'poe@daimi.aau.dk (Peter Orbaek)');
  
  $from->create('foo@bar.com' => 'Mr. Foo', poe => 'Peter');
  $from->parse('foo@bar.com (Mr Foo), Peter Orbaek <poe>');

  # make a RFC822 header string
  print $from->stringify(),"\n";

  # extract e-mail addresses and names
  @addresses = $from->addresses();
  @names = $from->names();

  # adjoin a new address to the list
  $from->set_address('foo@bar.com', 'Mr. Foo');
