-Notes:
-
-1. Large messages are fragmented in [Chrome's new WebSocket implementation](http://www.ietf.org/mail-archive/web/hybi/current/msg10503.html).
-2. The application can get the type of a received data message by implementing
- a [Codec marshal](http://godoc.org/golang.org/x/net/websocket#Codec.Marshal)
- function.
-3. The go.net io.Reader and io.Writer operate across WebSocket frame boundaries.
- Read returns when the input buffer is full or a frame boundary is
- encountered. Each call to Write sends a single frame message. The Gorilla
- io.Reader and io.WriteCloser operate on a single WebSocket message.
