connect to skulpt

[albertjan]

postpone making python types till in compiler

intermediate types can toString to the exact cpython value, while maintaining metadata to construct skulpt types.

drawbacks:

• our ast differs from cpythons because well use javascript types (with maybe annotation) we would need extra information to construct the right python type.

benefit:

• not tied to skulpts implementation

Adding another idea.
Another way we could integrate with skulpt might be to pass a space object as an argument to the parser
(I think this is what pypy does)

space would need to implement pyStr, pySyntaxError, pyAdd essentially everything inside the mock_types folder and internally we just use our mock_types.

An advantange here is that we don't need to double up on methods in production code. And we also don't need to rely on the window.Sk object being defined globally.
