Description for using functional components

[jugosack]

Per project requirements, If you already use functional components, you can create a GitHub issue in which you describe how you use functional components and ask for a code review based on your issue. As of React v16.8 it's recommended to only write functional components. You might see class components every once in a while, but it's discouraged to use them.

Per React docs: React components are regular JavaScript functions except:

• Their names always begin with a capital letter.
• They return JSX markup.

Functional components are preferred over class components:

• Functional components require less code which results in smaller file sizes.
• Functional components promote composition over inheritance.
• Functional components are stateless.

For this project, instead of using classes, it is created the Calculator.js and Input.js components as functional components in their respective files.
