/**
 * Shared base-class of all calendar UserInterface classes
 *
 * It manages eg. the state of the controls in the UI and generated the calendar navigation (sidebox-menu)
 *
 * 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
 *
 * All permanent debug messages of the calendar-code should done via the debug-message method of the bocal class !!!
