Added in high speed usb serial library (from Teensy web page)...capable of over
1mbps on late 2011 Macbook pro, which should be plenty for what we need.

Implemented two channel interleaved recording in arduino sketch by swapping the
ADC input pin at the end of each interrupt.
A simple serial reader using jSSC
(https://code.google.com/p/java-simple-serial-connector/), used to test data recieved from
Teensy/Arduino
Removed recording data (not for github)
