Communication class between DDserver and client.
ddnCmd is the class whose instances are passed between a remote DD client and its corresponding server on the host where the DD pool resides. It inherits from the class otnetObject the ability to be written/read into/from a socket.
A ddnCmd has two parameters, an integer which corresponds to the command code and an integer parameter, which can hold additional information if needed.
