An abstract schema for JSDoc

# api-json

`api-json` is a **documentation data standard**. It can be generated by
documentation engines like [documentationjs](https://github.com/documentationjs)
or written by hand.

`api-json` enables a two stage documentation process:

1. documentation extraction or authorship
2. output formatting

### Maximum example

```js
