closes#1807
- e2e tests now also cover the tax calculator.
- Dart app updated to match TS (it had no sales tax calculator).
- TS sample source cleanup (e.g. removed many unnecessary `docregions`).
- Prose updated to include @kwalrath's revisions from a while ago, Ward's comments, and
some of my edits as well.
Contributes to #1598 and #1508.
Update gulpfile and project to add a tsconfig to protractor test folders
Change all sample e2e-spec.js -> e2e-spec.ts
Split typings between e2e-spec & app code
Use same config for all e2e tests
Only 1/3 e2e specs truly converted.
Most don't pass because they fail TS transpile by Protractor due to missing type annotations
