Update Part 1 of the PySoy Primer to reflect our current API. The cube created by it should have a small radius and checkered material. Likewise add a sphere with a different checkered pattern. Use a Room instead of a Scene, a white background, and introduce some motion and collision. Clean up the narrative to match.

Upload the code for this to examples/PySoy_Primer1.py with the narrative part of the tutorial in comments.

Add screenshots to the wiki page showing the Box, Sphere, etc against a white background (no window edges) and a graphical tree of the objects and how the relate to each other (eg, Client -> Window -> Projector -> Camera).

While working on this task you should join and remain in #PySoy on Freenode to get help, feedback, and guidance from mentors and other developers.
