This API is intended to be used to interface with the hardware
that is running Mycroft. It exposes all possible commands which
can be sent to a Mycroft enclosure implementation.
Different enclosure implementations may implement this differently
and/or may ignore certain API calls completely. For example,
the eyes_color() API might be ignore on a Mycroft that uses simple
LEDs which only turn on/off, or not at all on an implementation
where there is no face at all.
