 * ESP8266 Web server with Web Socket to control an LED.
 *
 * The web server keeps all clients' LED status up to date and any client may
 * turn the LED on or off.
 *
 * For example, clientA connects and turns the LED on. This changes the word
 * "LED" on the web page to the color red. When clientB connects, the word
 * "LED" will be red since the server knows the LED is on.  When clientB turns
 * the LED off, the word LED changes color to black on clientA and clientB web
