super super super rough draft done. it spits out the right transform for the nea json file, but there's a lot of things to think about. E.g., we talk about commodities and recipes in cyclus. we only have inputs and outputs in the specification. Further, I feel like we're just translating into a cyclus meta-language. This is a brute force attempt, whereas a real attempt would require me to make mirror python objects for every cyclus object... let me know what you think
