/*
This example shows how to make an Extension Class "pickleable".
The world class below contains member data (secret_number) that
cannot be restored by any of the constructors. Therefore it is
necessary to provide the __getstate__/__setstate__ pair of pickle
interface methods.
The object's __dict__ is included in the result of __getstate__.
This requires more code (compare with pickle2.cpp), but is
unavoidable if the object's __dict__ is not always empty.
For more information refer to boost/libs/python/doc/pickle.html.
