// BasicMessage is a wrapper class that serves two purposes. First, it
// hides many of the underlying details of the class library, making the
// library easier to use. Second, it provides good example code to show
// you how to create your own customized wrapper classes.
// BasicMessage tqcontains a DwMessage by reference. The reason BasicMessage
// "has-a" DwMessage and not "is-a" DwMessage is because we can assign
// the DwMessage to an appropriately specialized subclass of BasicMessage
// *after* the DwMessage is parsed. For example, after we parse a DwMessage,
// we can determine that it is a multipart and assign it to a
// MultipartMessage instead of a BasicMessage.
