+CObexReaderBase provides obex specific reader behaviour for concrete readers to use.  
+Derive from this class when providing a reader for a specific transport.  
+
+In a concrete reader the following things must be done:
+(a) In DoTransfer a read data transfer is issued over the reader's transport
+(b) GetMaxPacketSize must return the maximum packet size that can be received
+(c) GetInitialPacketSize must return a packet size that can be used in the event  that the packet 
+size of the packet to be read  is not yet known (for example irda and bt use the obexpacketheadersize and usb
+uses the buffer size of the packet created to receive the data)
+(d)The NewL function must call BaseConstructL().  This is future proofing in the event that the iFuture1 variable is used
+and requires initialisation
