soy.joints.*.axis are currently arrays of float when they need to be instances of soy.atoms.Axis instead. Refactor the various examples of anchor property code (which uses soy.atoms.Position) for axis and update the bindings in PySoy appropriately. The following joints will be updated:

• Hinge
• Hinge2
• Piston
• Slider
• Universal

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.
