Tested removing tuple() without any problems.

SFVec3f field values converted to lists from tuples, to clarify. Good work!

I need to talk to you about making MF fields and nodes iterable. Output 
fails in both JSON and XML output.

See traceback here:


Traceback (most recent call last):

line 141, in <module>

    for each in self.children:

I'm hoping we can spend some collaboration time working on these 
issues.  Otherwise, I will try to engage my python programmer to discuss 
options.

Pretty much all my code has been posted except for removing tuple().
