    Description: To prevent the watchdog from excessive repeate notifications,
        the system administrator can set a minimum period for notification
        silence.  This class (CHistory) manages the reading of this setting
        along with remembering the last time an action occured.  A client
        of the object is able to ask it if a given action should be performed
        on the basis of past actions.
        
            CHistory
