    39 Implements MLogServTaskInterface and MLogServBackupObserver.

    40 Maintains a list of hitters, i.e. objects that will execute the requested by the client operation - add event, etc.

    41 Every time, when one of the implemented TaskEventAddL(), TaskEventChangeL() etc. methods is called, that method

    42 will read the client data and call the StartL() method of the hitter suitable for that operation.
