+Abstraction for transport controller implementations. Defines an interface to 
+be used by Obex protocol layer as the facade to the transport layer.
+
+In a concrete transport controller's NewL, the following things must be done: 
+(a) CObexTransportControllerBase::iConnector must be assigned to a 
+CObexConnector-derived type. (This may be reliant on the TObexTransportInfo 
+object passed in at this time.) iConnector is owned by 
+CObexTransportControllerBase.
+(b) CObexTransportControllerBase::iTransportInfo must be assigned to a 
+persistent (i.e. heap-based) TObexTransportInfo or derived type. The derived 
+transport controller may cast the TObexTransportInfo given at construction 
+time to a known derived type and copy the data from it to the new instance on 
+the heap. Note that ownership of the given TObexTransportInfo *remains with 
+the client*. iTransportInfo is then owned by CObexTransportControllerBase.
+
+In a concrete transport controller's NewTransportL, two instances of types 
+derived from CObexActiveRW must be created, and stored in 
+CObexTransportControllerBase::iActiveReader and 
+CObexTransportControllerBase::iActiveWriter. CObexTransportControllerBase owns 
+these.
