	idea główna 
	sprawdzać czy obiekt kalenadrza jest już zbudowany 
	
	budowąc ukryty i pokazać po zbudowaniu 
	jak nie to pokazać i wypełnić zawarotścią
	jak jest pokazany 
	to zmienić x i y oraz obiekt gdzie ma zwrócić wartość 
	
	po wybraniu dnia wyszczyścić obiekt i ukryuć go
	po wybraniu innego miesiąća albo roku przebudować kalendarz 
	ustalić style kalendarza od początku
