Some members of the community and proposal authors have been putting together a spreadsheet comparing type syntaxes that are in use in the community today (though not 100% comprehensive). For easier access, this PR adds it to the repo in markdown format.

The row for "Union type" is screwed up, probably due to conflict with markdown syntax.

For "Dotted/variadic polymorphism" for Flow, you can put "Same as TS" (we support tuple type spread)

For "casting syntax" (as) for Flow, you can put "Same as TS" (announcement coming soon)

Thanks for the feedback, I've updated the PR with all those points now.
