Adds runnable samples under samples/PivotTable demonstrating the pivot table feature, discovered automatically by the sample browser: - 01_Create_PivotTable: build a basic pivot (row/column/value fields) from a source range and save it as Xlsx. - 02_PivotTable_Page_Filter: add a page (report filter) field. - 03_PivotTable_Grouping: group a numeric field into ranges and a date field by quarter. - 04_Read_PivotTable: write a pivot, load it back, and inspect the pivot table object model (source, row/column/page fields, value aggregation). Directory is named PivotTable to match the PascalCase convention used by the other sample categories (Table, Chart, ...).
