[Backend] Auth

[avinashrao2002]

The goal is to have working auth for students to create an account and sign into sproul. For this task you will need to.

1. Create endpoints for creating an account and signing in. We want the user to input their email and password like so:

2. Create a schema for students in our backend and a table for it in DynamoDB. Since we don't have access to the rest of the backend right now, lets try to keep this independent of the other parts of the server so that you can run it and test it. Also for AWS you can use a personal account for now. Something that might make this task easier is creating a simple script that creates the tables in dynamo db so you don't have to rebuild them when we transfer to another account. You can look into that,but if you can't figure out how to do it, no problem.
