// Package tcsclient wraps the generated aws-sdk-go client to provide marshalling
// and unmarshalling of data over a websocket connection in the format expected
// by TCS. It allows for bidirectional communication and acts as both a
// client-and-server in terms of requests, but only as a client in terms of
// connecting.
