Interactive Comments section using React, Redux, Persist, Material UI

I just resubmitted this project, adding on Redux, React-Redux, Reselect, Redux-Logger, and Redux-persist. Now, currentUser and Comments are all in the redux store. I kept the toggle functions as react hooks because they needed to stay localized to the specific components they were mapped to.

Also, I used redux-persist in order to access local storage so the user's comments wont disappear when the page is reloaded.

Now that the code is much cleaner and organized, I notice that the modal window can be its own component. I'd like to fix that soon.

This is my first time using redux and its corresponding libraries all on my own, so comments on best practices, organization, etc are welcome!
