/**
* calendar UserInterface forms: view and edit events, freetime search
*
* The new UI, BO and SO classes have a strikt definition, in which time-zone they operate:
* UI only operates in user-time, so there have to be no conversation at all !!!
* BO's functions take and return user-time only (!), they convert internaly everything to servertime, because
* SO operates only on server-time
*
* The state of the UI elements is managed in the uical class, which all UI classes extend.
*
* All permanent debug messages of the calendar-code should done via the debug-message method of the bocal class !!!
