Added comments to sketch headers

Downgraded eclipse sketch to Processing 2.0b9

Downgrading from Eclipse to Processing is easier as a tool for teaching
others about the code. Eclipse isn't useful or necessary. Also
Processing 2.1 is buggy so I've downgraded the code and I'm using the
2.0b9 syntax again. Mainly printArray() => println()
Added GSR sensor code with Bluetooth
