Started code for Noel2013

# This script allows you to play music using a chorizo (or whatever food you
# like) keyboard ! See README for more info and links.
# Specially designed for our demo for Christmas 2013. Designed to fully handle
# 5 notes and play jingle bells.
# As all the other scripts in this repository, I release it under a very
# permissive license. To make a long story short : do whatever you want with
# this script (but try to have fun :), I don't mind. It would be cool to quote
# the origin of the script if you reuse it, but you don't have to. I'd like to
# be noticed of what you did cool with it (if you think it's worth). :)
# Ah, I almost forgot : If by chance we ever meet and you think this script is
# worth, you can buy me a soda :)

A script to play music using chorizo pads as a musical keyboard.

Launch `test_player.py` and use your keyboard to play music for now (A, B, C, D, E, F and G keys).

Our code for a demo at Christmas party 2013. We wanted to play Jingle Bells using a chorizo player, 5 notes to fetch from the array and map to real sound.
Use the same basis as `test_player.py` so it is also usable with a keyboard for fallback if whatever bad happen :)
