/**
 * Welcome to HuePebble
 *
 * Created By: Shervin Shaikh
 * Sends a message to MeshBlu (formerly SkyNet) to turn off Philips Hue lights from anywhere in the world!
 * There needs to be a client on the LAN of where the lights are on to listen for the incoming messages.
 * 
 * This code is from the app.js source file on a CloudPebble project.
 * Just create a new Pebble.js project and replace app.js with the code below, then build & run.
