+Socket 2 Event wrapper
+
+Author: Yentl Van Tendeloo
+
+This maps socket communication to events, and vice versa, allowing for a
+Statechart to use (blocking) sockets. It sends events to the socket_in port,
+and listens for commands on the socket_out port.  As this runs on its own
+thread, you will need to start the code by running
+"boot_translation_service(controller)" before using the ports.
