Books cart and checkout page

[s-orug]

This pr is for the carts page and the ability to add books to the cart.

Ok, I can:

• Add books to my cart
• Try to check out, and if I'm not logged in it will redirect me to login
• Check out once logged in

It cannot:

• deduct a user balance via mongo.

For my own note: we need to update the release notes with a customer account that has an ACTIVE balance for purchasing books

I am getting this error after running npm i already:

[wihobbs]

@rahulbulusu did you run npm i in both the client, backend, and root directories? remember there are separate package.json files in all of those

[rahulbulusu]

It works now I am looking at it right now

Everything looks to be working as seen from the screenshots. I didn't catch any bugs so awesome work on this Sai!!

This LGTM! I was able to check out and see the balance deducted. I went into Mongo and manually put 5k in [email protected]'s account (password email) and that's the account I'm going to give to Vidal.

I will give @jackcoberman until 1pm-ish to see if he has any changes. Then I'm merging and deploying this and we're calling Beta done.
