Added coneversion from ChipCap2 sensor input to actual sensor readings
(Humidity and Temp). Also create a stub program called
convert_sensor_TWI.c to show how this conversion works.
At this point two things could be done:

1.) Take multiple readings on the Atmel and convert the floating point
answer to it's 4 byte equivalent anwser and send that result to the
iPhone.

or

2.) Move decode algorithm to iPhone and run it there.
