/*
  Minimal Esp8266 Websockets Server

  This sketch:
        1. Connects to a WiFi network
        2. Starts a websocket server on port 80
        3. Waits for connections
        4. Once a client connects, it wait for a message from the client
        5. Sends an "echo" message to the client
        6. closes the connection and goes back to step 3

  Hardware:
        For this sketch you only need an ESP8266 board.
