+Original data collection script by Ben Kenney - July 2012
+This program reads data coming from the serial port and saves that data to a text file. It expects data in the following format with a comma (,) as a separator:
+"value1,value2"
+It assumes that the Arduino shows up in /dev/ttyACM0 on the Raspberry Pi which should happen if you're using Debian.
