Replace flow with TypeScript

[lencioni]

What do folks think? Should we switch everything over to TypeScript?

If we do, we can generate flow type definitions using https://github.com/joarwilk/flowgen.

After think about this some more, I think that staying with flow and generating TypeScript lib defs is probably the way to go. The API is pretty small so generating lib defs shouldn't be too bad. Flow's type safety is a lot better that TypeScript's. Beyond lib defs are there other reasons why we'd want to switch?

More people are familiar with TypeScript, so switching will make it easier for those folks to contribute to this project. And, as TypeScript's popularity continues to outpace Flow's, this will be increasingly the case.
