sl@0: Implements MLogServTaskInterface and MLogServBackupObserver.
sl@0: Maintains a list of hitters, i.e. objects that will execute the requested by the client operation - add event, etc.
sl@0: Every time, when one of the implemented TaskEventAddL(), TaskEventChangeL() etc. methods is called, that method
sl@0: will read the client data and call the StartL() method of the hitter suitable for that operation.
