GUI playground

[balbatross]

It's not quite as good as the Luna park editor but we've got an InfiniteCanvas component in use in our applications that would make for a passable GUI playground to visualize the cst tokens.

I'll look to make some progress in the next week or so.

@balbatross If you're looking to contribute, and especially to built on top, there's a lot of other work to be finished first! I've been using Notion to track work, but maybe it's time to move everything back here. That way if people are interested they can see what work remains to be done!

Since the easiest way to render a tree of tokens is to just print code, I was thinking that my first visual demo would be a simple syntax highlighting playground. So far no languages yet have complete working implementations. It doesn't matter yet because the core is broken, but anything I can do to help people write and test the necessary language definitions will be paid back many times over.
