"""
Simply little utility function to make it possible to pickle generators.
While generator instances can not actually be pickled, this saves the generator
function and only creates a generator instance when the first value is accessed.

The goal is to make it possible to pass generators, with arguments, through multiprocessing
which uses pickling internally to move objects between Python processes.
