The goal is to make a cross platform variant of [DatePickerIOS](https://facebook.github.io/react-native/docs/datepickerios.html) by implementing a Android variant with similar look and feel.

## TODO
- [x] Mode: datetime
- [x] Locale support. (AM/PM, 12h/24h toggled and strings translated)
- [x] Replace todays date with the string "Today" (considering locale)
- [ ] Animate to date when state change occur.
- [ ] Transparent background support. (Probably need to include transparent gradient).
- [ ] Align text to right.
- [ ] Mode: date
- [ ] Mode: time
- [ ] Support maximumDate/minimumDate. (Gray out and animate back to max/min value if exceeded).
