Use the NYTimes Best Sellers Books API to load a list of best-selling books in a collection view.

The User Interface should be created 100% programmatically (no storyboards or xibs).

Requirements:

• The user should be able to select different categories to view the best-selling books in that category.
• Selecting a book should segue to a Detail View Controller where the user can see more information about the book and favorite the book.
• Favoriting a book should save it to documents directory.
• The user should be able to view all the books that they have favorited.
• The user should be able to delete a favorited book.
• The user should be able to use a Settings page to set the default category that will be loaded in the list of recent best-sellers.
• Books added to favorites are sorted by most recently added date.

1. Best Sellers
2. Favorites
3. Settings

This view should have a:

• CollectionView

The collection view cell should include:

• The image of the books cover
