cleaning up...
Began implementation of MirrorAxis class
Works in one axis; need to make some modifications to get the other axis to work.
Fixed hang issue? Still has print statements for debug
Narrowed hang condition down to readSensor(); potential fix in adding false for repeated start to endTransmission()
Appears to work with the addition of 4.7K pullups and true in endTransmission()
Added samples; changed PID coefficients; added LICENSE headers
Remove print statements, add comments
removed superfluous print statement and unused code
merged KevinWork into master
