I branched off of strong-mode (see above to verify my request is to merge this branch there) and replaced Dart 2 API's new constants with the same constants defined in dart2_constant.
This will allow quantity to still be able to run in Dart 2 and Dart 1.
Primarily, I used dart2_constant/core.dart and dart2_constant/math.dart, which I named polyfill_core and polyfill_math respectively, to avoid confusion with SDK API.
