	 *			The problem is that number of days in week is dependent on the

	 *			properly. We should take into account the possibility that there's
	 *			not enough place for all days in the submitted frame.
	 *
	 *	\par	
	 *			The solution will be as follows:
	 *			Let number of days in week be N. I create two columns and 
	 *			several rows (the number depends on N). Days in week will be
	 *			proceeded in the order <em>as Calendar Module supplies them</em>.
	 *			The days occupy both columns, and are located in rows
	 *			[0, (ceiling of (N/2)) ). Days returned from CalendarModule are
	 *			placed as follows: days from 0 to (ceiling of (N/2)-1) in the left
	 *			column, days from (ceiling of (N/2)-1) to (N-1) in right column.
	 *
	 *	\par	
	 *			Two controls for setting the colors of weekdays and weekends
	 *			are located at the bottom row of the grid; weekdays on right,
	 *			weekends on left.
	 *
	 *	\par	
	 *			There will be an empty cell in the right column, if number
	 *			of days in week is odd.
