`width` & `height` are not accessible as globals across imported Python modules in the same directory

Unlike in Processing tabs that exist in the same folder, different Python modules in the same directory does not share width and height information. width and height have to be imported to the Class constructor for now as a workaround.

Example:
noc-2-mewnala-port > chapter2 > Example_2_6_Attraction

• width and height are declared in Example_2_6_Attraction.py setup
• Attractor.py and Mover.py are also trying to access width and height
  Note that there is no error anyway if we try to run the sketch without providing width and height to the Classes, but it isn't exposed to modules outside the one that has size(width, height) in the setup

Riproduci il comportamento in noc-2-mewnala-port/chapter2/Example_2_6_Attraction, dove setup definisce width e height mentre Attractor.py e Mover.py vi accedono. Inizia tracciando il modo in cui i moduli nella stessa directory ricevono lo stato di Processing; il lavoro è completato quando questi moduli possono accedere a width e height senza passarli ai costruttori delle loro classi.
