The row and column groups on a sheet, and how they are laid out.
Remarks
There is no group object to create or delete. Every row and column carries an outline level,
0 to 7 (ICellHeader.getOutlineLevel), and a group at level n is a run of
consecutive rows (or columns) whose level is n or more. Its summary row is the one just past
the run, on the side getSummaryDirection names. Collapsing a group hides its detail rows.

Collapsing a group hides its detail rows.Groups are made and removed with ICellRange.group and ICellRange.ungroup, or from the sheet's formulas with autoOutline, and collapsed and expanded with ICellRange.hideGroupDetails and ICellRange.showGroupDetails. Whether the symbols are drawn is the view's: ISheetView.setShowOutlineSymbols.
