/**

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
