Duh, use the 3.3 Volt regulator on the accel!

So there was a current issue with running directly off of the battery. I was getting variable readings on the accel when no accelerations were being applied. I'm no EE, so power supplies are a mystery to me. May be the unregulated power was experiencing boom and bust cycles like Wall Street.

Then I remembered the 3.3V regulator on the accel breakout from pololu. Now I run the power right into Vin on the accel and power the rest of the circuit off of the 3.3V regulated output-- fixed. I'd appreciate any better explaination if you know have one.

Now back to the software.
