The module implements the RPR220 IR Reflective Sensor. It was tested
with the Grove IR Reflective Sensor.
It includes 2 examples: rpr220.cxx, demonstrating the simple use case
of querying the current status.
rpr220-intr.cxx demonstrates the use of this class to register an
Interrupt Service Routine (ISR) to count transitions, which might be
more appropriate for some use cases, such as measuring RPM's.
