* Initial infrastructure for sourcecred-explorer.
Setup npm, yarn, flow, jest using scaffolding from
create-react-app.
- used create-react-app to get the basic pieces
- added support for flow via instructions in the
create-react-app user guide
- added flow-typed so that flow+jest will work well
* Add some additional resources
* Add index.css
* Remove .DS_STORE per @wchargin's suggestion
