feat: Added unauthenticated user model (#9)

Changes
1) Have made a shell for the backend of the project with routes, controllers and models
2) Have added a user model, route and controller. This only adds a user for now. Still it's not authenticated, and meant as a test

Additional content
1) Next we will authenticate the user and add several endpoints for signing up, logging in and loggin out
