- make Firmata a subclass of HardwareSerial
- per-pin digital callback, since the per-port callback is a bit complicated
for beginners (maybe Firmata is not for beginners...)
- simplify SimpleDigitalFirmata, take out the code that checks to see if the
data has changed, since it is a bit complicated for this example. Ideally
this example would be based on a call
- turn current SimpleDigitalFirmata into DigitalPortFirmata for a more complex
example using the code which checks for changes before doing anything
- test integration with Wiring
