Ordering attributes for dynamically generated class

Hi Aaron. Yeah, definitely sounds like a possibility. I was able to  
locate an ordered dict implementation that subclasses dict. This  
might work fine.  Might be able to pass into type method directly  
since I think that dict passed into type is setting __dict__ I  
believe.  Let you know if that works out. Many thanks.

Regards,
David
