Do the following exercises for this homework.

1. Upgrade your solution to homework 2 by adding:

   • An mLab-based, MongoDB backend for your person data. We suggest that you add a new collection to your current DB account. Implement all the routes specified in homework 2. As with the lab, create a cs336 user with the course password.
   • A React frontend that allows the user to see a list of people and add a person. Serve your frontend from the / route.

   Model your solution on the comments application built in the labs.
