/**
This class derives from the phonebook synchroniser plugin interface, but
contains no implementation.  It is used to avoid the deadlock situation which
occurs when the phonebook synchroniser server, using the Contacts Model, tries
to call itself.

The contacts server analyses the SID of the server process and replaces the
real plugin with this class.  As a result the check is only required in one
place where the plugin reference is requested and the algorithms using the
plugin are unaware of the replacement.
