Usage of `@providesModule`

Hey there,

This is really useful for people using prior versions, but using `@providesModule` makes this unusable for Expo folks because `rn-cli.config.js` doesn't exist with Expo. With Expo we have to wait for them to publish a new sdk before we can use the latest RN version, so changing your code to use relative imports instead of `@providesModule` would make it much easier for users to get access to FlatList+. Your code is in the same directory so you don't really need that special module resolution. Just throw a `./` in your requires and we all prosper.

Thanks for your work!

Search the JavaScript source for @providesModule and the require calls that depend on rn-cli.config.js; the issue says the relevant modules are in the same directory. Confirm the affected imports work without rn-cli.config.js in an Expo setup and that FlatList+ remains usable.
