/*
   KiteLib ESP8266 HTTP GET Example

   This example sends HTTP GET request using ESP8266 WiFi module.

   Please note that the response will be saved including header. HTTP header size
   can easily exceed Arduino resources and cause the program to behave erratically.

   IMPORTANT: Before uploading this example, make sure that the ESP8266 module is running
   AT firmware (can be found in the /extras folder of the library)!
