Removed three debug statments that were left in by mistake.
Initial commit of the hardware documentation. Includes reference sheets for the breakout boards from Adafruit, the pinout for the Arduino Uno, the data sheet for the ATmega328P, and a schematic of the daq as it is currently built.
Commands A R M P and D work. Added functionality to  the D command such that aDm retrieves the last m meansurments that were taken from port a. The EEPROM now holds up to the most recent 144 measurments.
Fixed a bug so that the D command now sends data in time forward order
Upadted the aDn command so that it returns correct number of measuremetns. see issue number 5 for a complete description.
Removed strange characters from comments in EEPROMex.h.  Arduino IDE was complaining about characters that were not UTF-8 encoded, and removing these characters corrected the complaining.
Merge branch 'Thermo' into commandQueue to incorporate Zak Pearson's
latest work on the DAQ unit into the version of the application that
attempts to reconnect to lost devices.
