Methods
Phase: Creating
- -  setControlPanel:-  (id <ControlPanel>) cp
Phase: Using
- -  doTkEvents-  A message that processes any input or output events of the Tk toolkit. Scheduling -doTkEvents ensures Tk keeps the user interface up-to-date.  Without scheduling it as part of the GUI code, the Tk events would just queue up and never get processed, resulting in a static, unresponsive user interface. 
- -  sendActionOfType:-  (id <Symbol>) type toExecute:-  (const char *) cmd
- -  insertAction: actionHolder
- -  setScheduleContext:-  (id <Swarm>) context
