Start the OpenID authentication process. See steps 1-2 in the
overview at the top of this file.

@param string $user_url Identity URL given by the user. This
method performs a textual transformation of the URL to try and
make sure it is normalized. For example, a user_url of
example.com will be normalized to http://example.com/
normalizing and resolving any redirects the server might issue.

@param bool $anonymous True if the OpenID request is to be sent
to the server without any identifier information.  Use this
when you want to transport data but don't want to do OpenID
authentication with identifiers.

@return Auth_OpenID_AuthRequest $auth_request An object
containing the discovered information will be returned, with a
method for building a redirect URL to the server, as described
in step 3 of the overview. This object may also be used to add
extension arguments to the request, using its 'addExtensionArg'
method.
