Description: ==========================================================
        Convinience for Datetime handling in combination with Zope
        ==========================================================
        
        ``bda.calendar.base`` contains functions adressing programmers all-day tasks
        not (or only partly) covered by pythons datetime or zopes DateTime.
        
        Major part of these function is timezone aware. Also ist easy to deal with
        timezones. An TimezoneFactory can be provided in the specific application
        to i.e. be aware of the users timezone (i.e. in case of webapps).
        
        
        calculators
        -----------
        
        CWof(date)
        the calendar week number of a date.
        
        firstDayOfCW(year, cw, tzinfo=None)
        first day of a numbered calendar week
        
        daysOfWeek(year, cw, tzinfo=None)
        yields 7 datetimes of the given calendar week
        
        numberOfDaysInYear(dt)
        calculate number of day of the year of the given datetime year
        
        numberOfDaysInMonth(dt)
        calculates number of days of the given datetimes month
        
        daysOfMonth
        yields all days as datetimes of the given month
        
        hoursOfDay(year, month, day, tzinfo=None)
        yields all hours of a day as datetimes
        
        isSameDay(first, second)
        detects if two dates are the same day. bool.
        
        
        converter
        ---------
        
        dt2DT(dt)
        Convert Python's datetime to Zope's DateTime. Acts timezone-aware.
        
        DT2dt(DT)
        Convert Zope's DateTime to Pythons's datetime. Acts timezone-neutral,
        outcome is on UTC.
        
        dt2UTCString(dt)
        build a '-' separated string from the datetime timetuple as UTC.
        
        dtFromUTCString(utcstr)
        build datetime from timetuple UTC string.
        
        dt2epochday(dt)
        Number of days since epoch.
        timezone gets a problem here, we need to normalize all to GMT to make it
        recognize the same day even if it a different timezone:
        i.e. 2008-05-01T00:00:00+02:00 (CEST)
        
        inspector
        ---------
        
        All functions are using the timezoneAdjuster (see below). therefore a context is
        passed
        
        dtYear(dt, context=None):
        year of datetime.
        
        dtMonth(dt, context=None)
        month of datetime.
        
        dtDay(dt, context=None)
        day of datetime.
        
        dtHour(dt, context=None)
        hour of datetime.
        
        dtMinute(dt, context=None)
        minute of datetime.
        
        dtWeekday(dt, context=None)
        Weekday of datetime.
        
        pyDt
        Detect wether dt is instance of datetime object.
        
        recurring
        ---------
        
        Simple recurring features. for more sophisticated recurring feature refer to
        dateutils.rrule
        
        recueDays(start, until, recuemode, offset)
        Generates list of recue days.
        
        
        timezone
        --------
        
        Dealing with timezones is always pain. With these common features it get less
        pain. Using ZCA where registering a common ``TimezoneFactory`` using the computers
        system timezone. It is used by the ``timezoneAdjuster``. If you register a more
        specific TimezoneFactory following its simple interface - its just a callable -
        , you can implement user configurated multi-timezone aware applications.
        This is all based on pytz, because pytz just works.
        
        ServerTimezoneFactory(context)
        The timezone of the server (current computer). You never need to use this
        directly.
        
        timezoneAdjuster(context, dt)
        New datetime with given timezone. Given datetime cant be naive!
        
        tzawarenow()
        timezone aware ``now`` datetime using utc timezone. if you need
        the current timezone adjust it.
