/**
 * A Message object represents a single message on the message bus.
 * Messages can contain either a data payload or an error payload.
 * Messages can be a command, or a response. An error notification is always a response.
 * The content of the payload is opaque and its format is only decodable by the sender(s) and the receiver(s)
 *
 * This has beeen simplified to remove TypeScript getters and setters, this is because, when using postMesssage()
 * and various other mechanisms because of The structured clone algorithm issue and deserialzing object properties.
 * You end up with an untyped object that only has the private properties ('_privateVar') exposed, none of the
 * methods either. Causes a dirty object that breaks most typed logic at runtime.
