/**
* \class Focuser
\brief Class to provide general functionality of a focuser device.
Both relative and absolute focuser supported. Furthermore, if no position feedback is available from the focuser,
an open-loop control is possible using timers, speed presets, and direction of motion.
Developers need to subclass Focuser to implement any driver for focusers within INDI.
