[KeenParchment]

Description / Changes Made

• Created a User Validation function to verify the data of a user is valid
• Added a create_user route that directly interacts with the Firebase database
• Tested the function to ensure it works with the Firebase

Screenshots

How to Test

1. Run the backend server
2. Using Postman, add the address http://localhost:5000 and set the Method to POST
3. Give the address a proper route /api/users. It can be seen in the screenshot above the route is: http://localhost:5000/api/users
4. Navigate to Body -> raw (ensure you are using JSON)
5. Include the body with its fields, to insert into the Firebase database
6. Click send and Postman will return the query in JSON format
7. Check the Firebase for the new user has been added (new unique ID should be created)
