// .NAME vtkExtractSelection - extract a subset from a vtkDataSet.
// .SECTION Description
// vtkExtractSelection extracts some subset of cells and points from
// its input dataset. The subset is described by the contents of the
// vtkSelection on its first input port. The dataset is given on its
// second input port. Depending on the content of the vtkSelection,
// this will use either a vtkExtractSelectedIds, vtkExtractSelectedFrustum
// vtkExtractSelectedLocations or a vtkExtractSelectedThreshold to perform
// the extraction.
// .SECTION See Also
// vtkSelection vtkExtractSelectedIds vtkExtractSelectedFrustum
