Utilizing the html injection feature of rustdoc, we can enable the use of $ \KaTeX $ in documentation!

For inline math, use $`1+1`$ , which renders as $ 1+1 $.

For display math, use:

```math f(x) = \int_{-\infty}^\infty \hat f(\xi)\,e^{2 \pi i \xi x} \,d\xi ```

(example taken from https://khan.github.io/KaTeX/), which renders as:

f(x) = \int_{-\infty}^\infty \hat f(\xi)\,e^{2 \pi i \xi x} \,d\xi

To enable this on docs.rs, you should be able to just add the following to your Cargo.toml:

[package.metadata.docs.rs] rustdoc-args = [ "--html-in-header", ".cargo/registry/src/github.com-1ecc6299db9ec823/katex-doc-0.1.0/katex.html", ]
