/**
 * Meant to be a simple version of a Websocket API that will run over: websocket (client only), 
 * raw tcp (java.nio.SocketChannel, client and server), 
 * Bluetooth socket (blocking input and output streams plus close).
 * 
 * Intermediate abstraction is (websocket client only) header read/to write and frame read/to write.
 * High-level follows Javascript Websocket API (http://www.w3.org/TR/websockets/) and is non-blocking and event-based.
 * 
 * Status: work in progress
 * 
 * Targets http://tools.ietf.org/html/rfc6455
