[Page] API

[marcustisater]

We need a page for visitors to look up API - We have to be smart here because there is a lot of documentation so we have to break it down into an anchor tag page.

API: https://github.com/postcss/postcss/blob/master/docs/api.md

Please read through our contributing guidelines before you start.
