CalendarConfigurationStory

Functional specifications

First steps in the webapp. The User should be able to log in and manage his/her subscriptions to the calendars.
On the frontend there should be:

• A page to log in, based on Basic Authentication
• A page with a List of calendars (each with a link to edit/remove them) and a button to add new calendars.
• A Page to add/edit the calendar information.

The layers below this must support the needed operations to list, store and remove the calendars in the database. Further more the layers below should be able to use iCalendar files (*.ics) located on http.

Perhaps we should make use of a baseclass for all persisted domain objects with the id. In the Spring manual is a chapter on how to make use of this to implement a base class for all hibernate dao implementations.
