=head1 NAME

Zurich FixMyStreet cobrand

=head1 DESCRIPTION

This module provides the specific functionality for the Zurich FMS cobrand.

=head1 DEVELOPMENT NOTES

The admin for Zurich is different to the other cobrands. To access it you need
to be logged in as a user associated with an appropriate body.

You can create the bodies needed to develop by running the 't/cobrand/zurich.t'
test script with the three C<$mech->delete...> lines at the end commented out.
This should leave you with the bodies and users correctly set up.

The entries will be something like this (but with different ids).

    Bodies:
         id |     name      | parent |         endpoint
        ----+---------------+--------+---------------------------
          1 | Zurich        |        |
          2 | Division 1    |      1 | division@example.org
          3 | Subdivision A |      2 | subdivision@example.org
          4 | External Body |        | external_body@example.org

    Users:
         id |      email       | from_body
        ----+------------------+-----------
          2 | dm1@example.org  |         2
          3 | sdm1@example.org |         3

The passwords for the users is 'secret'.

Note: the password hashes are salted with the user's id so cannot be easily
changed. High ids have been used so that it should not conflict with anything
you already have, and the countres set so that they shouldn't in future.
