Figure out a way to get browser PS runtime environment to try out PS libraries

[chexxor]

^ if I'm understanding the request correctly.

I'm unsure how it would look like, but @kRITZCREEK mentioned how nice Rust's libraries are because it's easy to get runnable code samples when browsing code. Something like here, perhaps: https://github.com/serde-rs/serde

Right now, TryPurescript is a nice environment to try PS libraries, but the prebuilt code samples need to be in a gist, whereas it might be more convenient to have the code samples in a lib's in-line docs or dedicated doc pages.
