Python enumeration with contextual grammar network?

[CatherineWong]

Since Python enumeration was resurrected for Puddleworld - I'm hitting an error now that makes me suspect that python enumeration doesn't work for the ContextualGrammarNetwork, given how primitive indices are stored?

Bug should be fixed, but let me know if it doesn't work.
