// protocol.h - This file defines two classes.  Encoder, and Decoder.
// It is expected that protocol definitions will multiply inherit from
// both of these abstract classes, and then define the members to deal
// with the protocol they are to provide support for.  It would
// therefore be possible to design a protocol that could only encode
// or decode, by inheriting from only one of the classes defined here,
// which would then cause a compile-time error if that protocol was
// used in the direction it does not support.
