Interface for the service that monitors the occurrences of system signals.
The signal to be monitored have to be declared via the method monitorSignal(). The method gotSignal() can used to check if a signal has been received.
Note that the service is passive, in the sense that it simply keeps track of received signals without performing any action. So it is responsibility of the users to add a check if the signal has been received or not.
