/**
A factory class, used for creation of operation objects and queueing them for execution.

Operation objects. Every operation class derives from CLogServOperationBase.

@see CLogServOpEventChange
@see CLogServOpEventDelete

@see CLogServOpViewSetup
@see CLogServOpViewEventRemove

View objects.Every view class derives from CLogServViewBase.

@see CLogServViewBase

@see CLogServViewEvent
@see CLogServViewRecent
@see CLogServViewDuplicate

The class also offers a factory method for views creation - NewViewL().
All created objects accept a reference to the MLogServOperationManager object and add themselves to the
operations queue.
