* refactor(nest): Better nesting implementation
This nesting implementation uses a proper recursive tree algorithm
Fixes https://github.com/documentationjs/documentation/issues/554
BREAKING CHANGE: referencing inferred destructure params without
renaming them, like $0.x, from JSDoc comments will no longer
work. To reference them, instead add a param tag to name the
destructuring param, and then refer to members of that name.
Before:
```js
/**
* @param {number} $0.x a member of x
*/
function a({ x }) {}
```
After:
```js
/**
* @param {Object} options
* @param {number} options.x a member of x
*/
function a({ x }) {}
```
* Address review comments
* Reduce testing node requirement back down to 4
* Don't output empty properties, reduce diff noise
* Rearrange and document params
* Simplify param inference, update test fixtures. This is focused around Array destructuring: documenting destructured array elements with indices instead of names, because the names are purely internal details
* Use temporary fork to get through blocker
* Add support for interface declarations
* Support exported interfaces/type aliases
* Update test fixtures
* Add interface type, fix test
* Fix comment style and typo
* fix(scopes): Support inner scope
The purpose and usage of inner is still unclear, unfortunately, so this is an interim fix at best.

* Improve comment typedef while we're at it
* feat(core): Switch to Promises everywhere. Adopt Node v4 ES6
Big changes:
* Uses template strings where appropriate
* Config and argument parsing is unified and there is no such thing
as formatterOptions anymore. All user-passed options go through
mergeConfig.
* The node API surface changed (again): `buildSync` is removed,
building operations return Promises.
* Now using Flow for internal type annotations.
More changes:
* Remove buildSync command
* feat(inference): Partially implement object shorthand support
* Refs #649
* Use Flow annotations to enforce types
* Keep flow but switch to comment syntax
* Clarify types
* More flow improvements
* Turn server into class
* LinkerStack becomes class too
* Fix comment description type
* Run flow on lint
* Many more flow fixes
* More intense flow refactoring
* Simplify inference steps
* Update inference tests, flow errors down to 1
* Continue refining types
* Fix more flow issues
* Use 'use strict' everywhere
* Make 'ast' property configurable
* Fix many tests
* Fix more tests
* Fix more tests
* Fix augments
* Test Markdown meta support
* Improve test coverage
* Switch back from for of to for for speed
