class google_map(http.Controller):
    '''
    This class generates on-the-fly partner maps that can be reused in every
    website page. To do so, just use an ``<iframe ...>`` whose ``src``
    attribute points to ``/google_map`` (this controller generates a complete
    HTML5 page).

    URL query parameters:
    - ``partner_ids``: a comma-separated list of ids (partners to be shown)
    - ``partner_url``: the base-url to display the partner
        (eg: if ``partner_url`` is ``/partners/``, when the user will click on
        a partner on the map, it will be redirected to <myodoo>.com/partners/<id>)

    In order to resize the map, simply resize the ``iframe`` with CSS
    directives ``width`` and ``height``.
