Added shofanduino2 program, much simpler since some of the calculations are now done in the sensor (filtering out noisy values).

Instead of 'avg' and 'max', we use envelope min
and max values that try to hug the humidity with
a slow moving function. The slow moving function
is based on the half-life equation, so the
parameters are more intuitive.
