Consuming SPFx Service Scopes using React Hooks

Summary

This web part is designed to help developers understand how to use the Context API and useContext() React Hook to share global data between a hierarchy of nested React components. In this example, a Service Scope is shared globally that components can consume to call the Microsoft Graph, it also uses Functional Components replacing the more commonly seen Class Component approach.
