This app is responsible for managing users, user authentication and teams. Multiple users together can form a team. The team can be used to share patterns. A user can be part of multiple teams. A user can also be part of no team. Users are created using the front end, which uses AWS Congnito to authenticate users. This app handles the authentication using the JWT (JSON Web Token) provided by AWS Cognito. We convert the JWT to our custom Django user object. This user object is then used by the rest of the application.
