// .NAME vtkExtractSelectedThresholds - extract a cells or points from a
// dataset that have values within a set of thresholds.
// .SECTION Description
// vtkExtractSelectedThresholds extracts all cells and points with attribute
// values that lie within a vtkSelection's THRESHOLD contents. The selecion
// can specify to threshold a particular array within either the point or cell
// attribute data of the input. This is similar to vtkThreshold
// but allows mutliple thresholds ranges.
// 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.
