/**
The CPplContactItemManager implements the MLplPersistenceBroker.

MLplPersistenceBroker is a public interface responsible for carrying out the
basic crud operations (Create, Read, Update, Delete). It is exposed to the users 
of Persistence Layer making the CPplContactItemManager an entry point for these 
operations.

CPplContactItemManager is responsible to forward the Create, Delete and Update calls
to the CPplTableBase based object representing actual tables in the contact database.
CPplContactItemManager holds the knowledge of the database structure: how many tables
and what tables compose the contact database.

The Read operation is managed inside CPplContactItemManager and not passed to the table
classes.
