Docs Requirements

Lessons learned from trying to implement this issue. Overall, the state of JavaScript API docs automation is pretty crappy.

• [ ] Inherit docs from super class: @override (No existing workaround with Documentation)
• [ ] Callback functions: @callback (No existing workaround with Documentation)
• [ ] Template variables: Array<T> using proposed @template (No existing workaround with Documentation)
• [x] Typedefs
• [x] Factory constructor functions: Called without new (Workaround in Documentation is to use @function in conjunction with @constructor)
• [x] Rest args
