Music to the Light Code

/*
A simple node.js application intended to read data from Analog pins on the
Intel based development boards
such as the Intel(R) Galileo and Edison with Arduino breakout board, and
display it in a browser running on the client.

This demonstrates use of http.createServer, and fs.

MRAA - Low Level Skeleton Library for Communication on GNU/Linux platforms
Library in C/C++ to interface with Galileo & other Intel platforms, in a
structured and sane API with port nanmes/numbering that match boards &
with bindings to javascript & python.

Steps for installing MRAA & UPM Library on Intel IoT Platform with
IoTDevKit Linux* image
Using a ssh client:
1. echo "src maa-upm http://iotdk.intel.com/repos/1.1/intelgalactic" >
/etc/opkg/intel-iotdk.conf
2. opkg update
3. opkg upgrade
