* This is a simple base class that other feature types will
* extend. A Feature is taken to be some capability of
* a Device that is relatively self-contained. For instance,
* an analog output voltage would be a Feature. Features can
* also contain multiple functions; for instance, a TEC may
* be able to report a temperature, take a temperature as a
* set point, and turn on or off. These capabilities are
* interrelated, and would be considered a single feature.
