[x3d-public] X3DJSAIL Python: setShape() Method not found on CollidableShape parent interface, cannot find in returned object. Need cast.

[John Carlson]

We need the right style to cast abstract returned objects to concrete objects in python.  See attached example.

processScene.python:
     [exec] Traceback (most recent call last):
     [exec]   File "C:\x3d-code\www.web3d.org\x3d\content\examples\Basic\RigidBodyPhysics\UniversalJointfuture.py", line 73, in <module>
     [exec]     .setDEF("BOX-GEOM-1") \
     [exec] AttributeError: 'org.web3d.x3d.sai.RigidBodyPhysics.X3DNBodyCollida' object has no attribute 'setShape'
     [exec] Result: 1
     [echo] C:\x3d-code\www.web3d.org\x3d\content\examples\Basic\RigidBodyPhysics\UniversalJointfuture.py

We should probably grant a prize to whoever gets the right casting that works in all instances.

My best bet for short term is to fold the setDEF into the object constructor.

What do people think?
