+ *
+ * 1) Rationale: Why listbox layout calculations are needed
+ *    -----------------------------------------------------
+ *
+ * Week view implementation differs from LAF specification. 
+ * LAF specification defines week view grid and time pane in the left side of grid. 
+ * But implementation uses listbox which combines both grid and time pane.
+ * 
+ * Implementation implements week view as specially customized Uikon listbox. Uikon listboxes have
+ * list items (= list rows), which have several subcells (rectangle inside row).
+ * For week view listbox, first column is for hour labels, and it can't be focused.
+ * Next 7 columns are for day columns of scrollable grid. Each row is one list item. 
+ *
+ * Following images might help you to imagine the idea: 
+ *
+ * Week view:

+ *
+ * 2) (Naming) conventions explained 
+ *    ------------------------------
+ * 
+ * Following conventions are used:
+ * - TAknLayoutRect/TAknLayoutText are written similar way as Avkon Layout system functions:
+ *   lower case, with underscore _ separating words. 
+ *   e.g. TAknLayotRect cale_week_time_pane 
+ * 
+ * - TRect types has _Rect ending 
+ *   e.g. TRect main_pane_Rect 
+ * 
+ * - cached (member variables) have i_ in the beginning
+ *   e.g TAknLayoutRect i_grid_cale_week_pane
+ * 
+ * - Layout values that can't be read from layout data but has to be calculated are always TRects. 
+ *   They have Rect ending. They are written in CamelCase, e.g. ListBoxRect
+ * 
+ * - all layout rects are main pane relative unless otherwise noted. Especially data that is read through layout APIs 
+ *   is always main pane relative because parents are passed to LayoutRect functions
+ * 
+ * - if layout rect is not main_pane relative, it is indicated by writing layout rect that it is relative to in the end
+ *   of name: e.g. hourCellRect_in_ListItemRect 
+ *   We only need ListItemRect relative stuff, because listbox subcell rects are given as list item relative.
