Angular template with repeater.

  * Converted the static HTML list into a dynamic one by:
    - creating PhoneListCtrl controller for the application
    - extracting the data from HTML into a the controller as an in-memory
      dataset
    - converting the static document into a template with the use of
      `ngRepeat` directive which iterates over the dataset with phones,
      clones the ngRepeat template for each instance and renders it into the
      view
  * Added a simple unit test to show how to write tests and run them
    with Karma and Jasmine
