Creating a custom UITableViewCell for our contacts

To display contacts in your UITableView, you will must set up a few more things. First and foremost, you'll need to create a UITableViewCell that displays contact information. To do this, you'll create a custom cell by creating a subclass of UITableViewCell. The design for this cell will be created in Interface Builder. To make the views added to the cell in Interface Builder available to our code, @IBOutlets are added to the UITableViewCell subclass. These @IBOutlets are the connections between the visual layout in Interface Builder and your code.
