User model

Currently, the Person model has a One-To-One Link With the User model. This is based on:

• simple is better than complex: How to Extend Django User Model
  • Django documentation - Database transactions: Controlling transactions explicitly
  • Django documentation - Using the Django authentication system: The login_required decorator
• Django documentation - Customizing authentication in Django: Extending the existing User model

Another option for changes in the future is a custom user model

• /var/: Use a custom user model
• Django documentation - Customizing authentication in Django: Using a custom user model when starting a project
