    SSHProtocolChecker is a checker that requires multiple authentications
    to succeed.  To add a checker, call my registerChecker method with
    the checker and the interface.

    After each successful authenticate, I call my areDone method with the
    avatar id.  To get a list of the successful credentials for an avatar id,
    use C{SSHProcotolChecker.successfulCredentials[avatarId]}.  If L{areDone}
    returns True, the authentication has succeeded.

        Part of the L{ICredentialsChecker} interface.  Called by a portal with
        some credentials to check if they'll authenticate a user.  We check the
        interfaces that the credentials provide against our list of acceptable
        checkers.  If one of them matches, we ask that checker to verify the
        credentials.  If they're valid, we call our L{_cbGoodAuthentication}
        method to continue.
