* Interface for a timer task.
* Timer tasks are created by the system and can be installed by the system.
* After installation, the timer callback-procedure or "timerProc" will be called
* periodically. You should not need to inherit this class. It is passed to the
* application in the timer-callback.<br>
* <br>
* Note that GHOST processes timers in the UI thread. You should ask GHOST
* process messages in order for the timer-callbacks to be called.
