Generator support?

[steven-johnson]

It would be super-cool if this tool worked directly with Halide code packaged as Generators, in addition to ordinary Halide code that just calls realize() directly.

(If it already works well with Generators, please ignore.)

I think it is possible, the only issue would be to ensure the Input<> buffers used by the generator have some data bound to them. That could be done by asking the user through file dialogs to bind images to each Input<>, or through some init file.
