Add in Localization

[code-jenn-or]

This library looks promising: https://github.com/react-native-community/react-native-localize

But determine how we can help scaffold this out.

From @cball

I’ve heard react-native-localize and i18n-js are the tried and true combo (theres an example in the react-native-localize github. this blog takes a slightly different approach, but either way it would be great to 1) nail down what to use and 2) implement it

big wins imo:

• we write it the same way if other languages are required or not
• better testing (we don’t test exact strings)
• additional language support should be pretty easy to add in

Consider implementing react-native-localize and i18n-js
