Weak Method

The WeakMethod is used by the Clock class to allow references to a bound method that permits the associated object to be garbage collected. Please refer to examples/core/clock_method.py for more information. This WeakMethod class is taken from the recipe http://code.activestate.com/recipes/81253/, based on the nicodemus version. Many thanks nicodemus!
