Here's the initial PR @benkeen

• Updated babel dependencies
• Updated eslint plugins and used it on files
• Updated tests to use jest and the react testing library
• Exporting dropdowns with forward ref
• Components using hooks

Still need to probably update readme and examples (the forward ref example)

So its nearly complete but it would be good to get some feedback.

Great stuff, @dojr! I'd taken a bit of a break from this script but just merged in a change for a blacklist/whitelist option for the Region field. But your additions look terrific. Perhaps what I'll do is get a new release for those changed I just added, but then merge yours in section. They look like a good general update for the code.
