=head1 DESCRIPTION

This class stores information about a person, most commonly an author of
a site or a document.

This class can parse plain strings like C<< Doug Bell <doug@example.com> >>
into an object with name and e-mail set correctly.

Person objects stringify into the C<name> field, for
backwards-compatibility.
