//A class for representing a virtual node. A virtual node is a state machine for handling
// one or more application-level protocols. Each board must implement at least one virtual node.
// Generally, this class will not be subclassed directly, but rather through one of the intermediate
// abstract base classes Event_Handler, Datagram_Hander, or Stream_Handler, depending on the
// transport method used by the protocol.
