Api-error-handling

I recently upgraded this project to React 18 using a top-level React class component AND functional components. The class component contains the state, and the other components contain the props.

This version of the Monsters API app utilizes React 18, functional components, AND hooks.

This client side version the OMDB API app addresses potential built-in API errors. I felt it important to introduce my students to application error handling and thus a basic form of "testing".
