No, don't introduce circular dependencies, and make it explicit what your
functions operate on by passing things as parameters, instead of using
global references.

It is *much* more preferable to pass 'storeList' as a parameter to your
functions. Don't change things behind the scenes.

file: Initialise.py

Keep it the way it is. It's wrong on too many levels to do it the other way.
