Design and implement a RESTful web service to facilitate a user authentication system. The authentication mechanism should be token based. Requests and responses should be in JSON.

Models

The User model should have the following properties (at minimum):

1. name
2. email
3. password

You should determine what, if any, additional models you will need.

Endpoints

All of these endpoints should be written from a user's perspective.

1. User Registration
2. Login (token based) - should return a token, given valid credentials
3. Logout - logs a user out
4. Update a User's Information
5. Delete a User
