/*! \par Notes on implementation:
* It's not all that straightforward - to create this selection box.
* The problem is that number of days in week is dependent on the
* Calendar Module, therefore the frame rectangle must be divided
* 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
* There will be an empty cell in the right column, if number
* of days in week is odd, (which is usually the case).
