/** Receives notifications from transport.

This is provided as a way of retaining BC for the CObexClient and 

CObexServer classes.

This class implements the MObexNotifyExtend interface which is provided

to the transport.  Functions can safely be added to MObexNotifyExtend to 

allow the transport to provide additional notifications in future without

altering the vtable for the published classes.  

A CObex owns a CObexNotifyHandlerBase.  The CObexNotifyHandler base

should not be instantiated directly, instead one of the derived classes

should be used.  The derived class then knows the type of the CObex

object created it, as the constructor will require an appropriately

derived type.  This allows the non-virtual functions in the appropriate

class to be called to handle notifications.

Functions that are generic CObex functions, rather than functions that

are handled differently by CObexClient and CObexServer, may be implemented

in the base class.
