/**

The RPplIccContactStore class works as an adaptor between the Persistence Layer

and the phonebook synchroniser server.

From one side it behaves like a Persistence Layer table and is registered as a

child of the Contacts table.  This is achieved by implementing the

MPplContactItemPersistor interface.

From the other side it uses the contact synchroniser plugin to communicate with

the phonebook synchroniser.

Since DBMS and all the tables in the Persistence Layer support transactions and

the phonebook synchroniser does not, the RPplIccContactStore class takes this

responsibility.  The class implements the MLplTransactionManager interface and

uses an internal array to keep all the actions required for transaction rollback

during the transaction.
