Jon Trulson b0625e11f1 wheelencoder: Initial implementation
This driver was developed for the DFRobot Wheel Encoder, though it
could be used for any counting time-based task using a digital i/o pin
to generate interrupts.

If you want to use more than one encoder, simply create a class
instance for each one.
