"Hello World" Actuator for OpenC2 Messaging

A stub server demontrating the content- and transport-agnostic OpenC2 Message interface.

A message is a logical unit consisting of domain-specific content plus an accompanying set of domain-independent fields. The purpose of this code is to show that a message is transferred end-to-end without modification regardless of the transport protocol, while making use of the message-related capabilities provided by each transport protocol.
