Improve documentation website.

[egoist]

Hi just FYI, the website (https://vic.github.io/laminar_cycle/) is broken, you need to remove root option from index.html .

base: '/laminar_cycle/ is also needed for correctly setting the link of site title.

Thanks for the heads up.

I still have a lot of work to do regarding documentation. Split the README into a proper guide -on core concepts- and documentation/examples for each driver.

Most likely the docs/ directory will move from using docup to scalameta's mdoc since the later provides compile time checks for scala examples.

I'll rename this issue and keep it open to remind me of tackling this.
