User must be able to create an account and log in.
When logged in, a user can see, edit and delete his times he entered.
Implement at least three roles with different permission levels: a regular user would only be able to CRUD on their owned records, a user manager would be able to CRUD users, and an admin would be able to CRUD all records and users.
Each time entry when entered has a date, distance, and time.
When displayed, each time entry has average speed.
Filter by dates from-to.
Report on average speed & distance per week.

All actions need to be done client side using AJAX, refreshing the page is not acceptable.
