// .NAME vtkExtentTranslator - Generates a structured extent from unstructured.
// .SECTION Description
// vtkExtentTranslator generates a structured extent from an unstructured
// extent. It uses a recursive scheme that splits the largest axis. A hard
// coded extent can be used for a starting point.
// .SECTION Caveats
// This object is still under development.
