    Description: A system administrator is able to specify control parameters
        for the watchdog.  These include:
        
            Show popup dialog to user (yes/no)
            Send user email message (yes/no)
            Minimum period between popup dialogs (minutes)
            Minimum period between email messages (minutes)
            Add users to "To:" email list <email address list>
            Add users to "Cc:" email list <email address list>
            Add users to "Bcc:" email list <email address list>

        A client of the object is able to ask it if a given action should be
        performed (dialog, email) and for the additional email names.
