Use:          Herevents(state);
              bool state - determines whether events are generated or not.
            
Description:  This function can be used in event-driven tasks to temporarily
              prevent Hermes from generating events such as keyword events.
              This can be useful when the current interaction is
              exclusively controlled by an other event source, e.g. a
              a plotfield cursor. In such cases the responsiveness
              of the application may improve.
