step-5 Filtering Repeaters

- Add a search box to demonstrate:
  - How the data-binding works on input fields.
  - How to use the `filter` filter.
  - How `ngRepeat` automatically shrinks and grows the number of phones in the view.
- Add an end-to-end test to:
  - Show how end-to-end tests are written and used.
  - Prove that the search box and the repeater are correctly wired together.
