/*
* SANKI 2016 03 31
*
* This sketch demonstrates how to set up a simple HTTP-like server.
* The server will set a GPIO pin depending on the request
* http://server_ip/gpio0 will set the GPIO0 high/low,
* http://server_ip/gpio2 will set the GPIO2 high/low
* server_ip is the IP address of the ESP8266 module, will be
* printed to Serial when the module is connected.
*
* Before RUN :
* Change SSID and Password
* Change port number
*
