Detailed Description

Pan/tilt act thread.

This thread integrates into the Fawkes main loop at the ACT_EXEC hook and interacts with the controller of a particular pan/tilt unit. Note that this abstract class is then implemented by threads interacting with a particular pan/tilt unit.

Each implementation of this thread shall open an instance of a PanTiltInterface and act within this thread's loop() method. The data read back from the unit shall be written in the update_sensor_values() method, that is called from the PanTiltSensorThread.
