The idea that I get from dogpile, is that in each module (getter.py, or setter.py) there is a dictionary where the values are stored in the backend. Hence, getter.py has its dictionary and setter.py has its dictionary also. In the end, there is not a single dictionary where all the values should be put. And I want a single dictionary.
