CObexWriterBase provides obex specific writer behaviour for concrete writers to use.  
Derive from this class when providing a writer for a specific transport.  

In a concrete writer the following things must be done:
(a)In DoTransfer a write transfer is issued over the writer's transport
(b)The NewL function must call BaseConstructL().  This is future proofing in the event that the iFuture1 variable is used
and requires initialisation
