Write several small unit tests for creating multiple Scenes, adding and removing bodies from them, moving and colliding bodies within them, moving bodies from one scene to another, and deleting scenes without and with bodies still within.

Some of these tests may fail, and some may even currently cause a segfault. Extra credit if you find a bug with your tests and post a ticket for it.

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. Code updates which may affect your work are also announced here as they happen.

When you've done, commit your work and post the resulting changeset url to this task.

The task "PySoy: Make Scene a Dict of Bodies" must be complete before this task can be assigned.
