Error Handling

1. Create an ErrorBoundary component. Your component should:

• implement componentDidCatch() which should set the state to indicate that an error occurred
• render its children
• if an error happened, render an error message instead

2. Wrap this component around your ContactListContainer component

• This component doesn't currently throw errors. Modify it to throw an error if it cannot contact its server.

3. Test your ErrorBoundary component to ensure that it renders the correct content whether an error occurs or not.
