`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

Reproduziere das Verhalten in noc-2-mewnala-port/chapter2/Example_2_6_Attraction, bei dem setup width und height definiert, während Attractor.py und Mover.py darauf zugreifen. Beginne damit nachzuverfolgen, wie Module im selben Verzeichnis den Processing-Zustand erhalten; fertig ist es, wenn diese Module auf width und height zugreifen können, ohne sie an ihre Klassenkonstruktoren zu übergeben.
