=head1 NAME
Class::Accessor::Chained - make chained accessors
=head1 SYNOPSIS
package Foo;
use base qw( Class::Accessor::Chained );
__PACKAGE__->mk_accessors(qw( foo bar baz ));
my $foo = Foo->new->foo(1)->bar(2)->baz(4);
print $foo->bar; # prints 2
=head1 DESCRIPTION
A chained accessor is one that always returns the object when called
with parameters (to set), and the value of the field when called with
no arguments.
This module subclasses Class::Accessor in order to provide the same
mk_accessors interface.
