In this section, you will add the show, index, and delete methods to users and admins. Chapter 1 will focus on providing these methods for the user class, and Chapter 2 will focus on providing these methods for the admin class.
Normally, it would be better to focus on the show, index, and delete methods individually instead of tackling them all at once. However, given that this protocol operates with the benefit of 20-20 hindsight, these methods are tackled all at once in the interest of not having to revisit key files and lines repeatedly.
