// .NAME vtkExtractSelectedIds - extract a list of cells from a dataset
// .SECTION Description
// vtkExtractSelectedIds extracts a set of cells and points from within a
// vtkDataSet. The set of ids to extract are listed within a vtkSelection.
// This filter adds a scalar array called vtkOriginalCellIds that says what
// input cell produced each output cell. This is an example of a Pedigree ID
// which helps to trace back results. Depending on whether the selection has
// GLOBALIDS, VALUES or INDICES, the selection will use the contents of the
// array named in the GLOBALIDS DataSetAttribute, and arbitrary array, or the
// position (tuple id or number) within the cell or point array.
