class Signal.

A simple implementation of the Signal/Slot pattern. To use, simply create a Signal instance. The instance may be a member of a class, a global, or a local; it makes no difference what scope it resides within. Connect slots to the signal using the "connect()" method. The slot may be a member of a class or a simple function. If the slot is a member of a class, Signal will automatically detect when the method's class instance has been deleted and remove it from its list of connected slots.
