ToDo without StoryBoard

- updated app delegate to set rootviewcontroller
- removed initWithCoder & replaced with initWithStyle
ToDo - Extracting a new method getListItem

- Moving 3 lines of code into a new method, so that we can reuse those
same lines of code somewhere else.
ToDo - No changes. Just reformatting.

- Used the built-in ‘tidy’ command (Structure -> Reindent) to correct
indentation.
- Removed blank lines.
ToDo - Allow users to be selected

- We can now select users in the table, and currently just print the
selected user’s name to the console.
ToDo - Adding Navigation Bar

- Updated rootViewController to now be of type UINavigationController
instead of a TableViewController.
- When a user is selected in our table list, it now opens a new view.
