0bcd7e6f41 Add new_env method 
This is basically the same as the one on the evaluator and makes use of
the ScopeStack - maybe need to generalize this more?

9bb3a2be88 Add type data handle on Node 
I think the way I want to handle this is a two-step process: first infer and
fill in variables, then unfiy in a separate step. Storing the data in
the AST is handy.
