Added check sum to packet out from Atmel. The input to the ADC is still
being hung up. I believe this is due to the interrupt that samples the
ADC not being called bc of the manditory keep out we have for sending
data.

Possible fix is a counter that takes a set number of ADC values before
sending the out.
Working on fix for ADC reading being blocked out by packets being sent
out.
Two way communication working with a Known sent value. Next step is to
send sensor data.
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.
