Reorganize and rewrite examples

Browse Source 
This commit is a large-ish scale reorganization of our examples. The
main goal here is to have a dedicated section of the guide for example,
and all examples will be listed there. Each example's `README` is now
just boilerplate pointing at the guide along with a blurb about how to
run it.

Some examples like `math` and `smorgasboard` have been deleted as they
didn't really serve much purpose, and others like `closures` have been
rewritten with `web-sys` instead of hand-bound bindings.

Overall it's hoped that this puts us in a good and consistent state for
our examples, with all of them being described in the guide, excerpts
are in the guide, and they're all relatively idiomatically using
`web-sys`.

# `--no-modules`
# Using `--no-modules`
This directory is an example of using the `--no-modules` flag and how it
integrates with the rest of the HTML/JS used.
[View documentation for this example online][dox]
[dox]: https://rustwasm.github.io/wasm-bindgen/examples/no-modules.html
You can build the example locally with:
```
$ ./build.sh
```
(or running the commands on Windows manually)
and then opening `index.html` in a browser should run the example!

// The `--no-modules`-generated JS from `wasm-bindgen` attempts to use
// `WebAssembly.instantiateStreaming` to instantiate the wasm module,
// but this doesn't work with `file://` urls. This example is frequently
// viewed by simply opening `index.html` in a browser (with a `file://`
// url), so it would fail if we were to call this function!
//
// Work around this for now by deleting the function to ensure that the
// `no_modules.js` script doesn't have access to it. You won't need this
// hack when deploying over HTTP.
