+Maintains a list of hitters, i.e. objects that will execute the requested by the client operation - add event, etc.
+Every time, when one of the implemented TaskEventAddL(), TaskEventChangeL() etc. methods is called, that method
+will read the client data and call the StartL() method of the hitter suitable for that operation.
