DESCRIPTION
    This module implements 'Google Contacts Data API' according
    <http://code.google.com/apis/contacts/docs/3.0/developers_guide_protocol
    .html>

    NOTE This new interface is still quite untested. Please report any bugs.

CONSTRUCTOR
  new( username => .., password => .. )
    *username* and *password* are required arguments and must be valid
    Google credentials. If you do not have a Google account you can create
    one at <https://www.google.com/accounts/NewAccount>.

METHODS
  $google->new_contact
    Returns a new empty WWW::Google::Contacts::Contact object.

  $google->contact( $id )
    Given a valid contact ID, returns a WWW::Google::Contacts::Contact
    object populated with contact data from Google.

  $google->contacts
    Returns a WWW::Google::Contacts::ContactList object which can be used to
    iterate over all your contacts.

  $google->new_group
    Returns a new WWW::Google::Contacts::Group object.

  $google->group( $id )
    Given a valid group ID, returns a WWW::Google::Contacts::Group object
    populated with group data from Google.

  $google->groups
    Returns a WWW::Google::Contacts::GroupList object which can be used to
    iterate over all your groups.

DEPRECATED METHODS
    The old module interface is still available, but its use is discouraged.
    It will eventually be removed from the module.
