* @class vtkExtractSelectedIds
* @brief extract a list of cells from a dataset
*
* 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.
