Notes:
- 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.
- The application can get the type of a received data message by implementing a Codec marshal function.
