Correctly set GlobalPointIndexStart and GlobalPointDimensions on output CellSetStructured after calling vtkm::filter::entity_extraction::ExtractStructured.

  • GlobalPointIndexStart is GlobalPointIndexStart of input CellSetStructured + minimum index of VOI
  • GlobalPointDimensions is copied from input CellSetStructured
  • Add a test to see if both GlobalPointIndexStart and GlobalPointDimensions are set correctly after calling filter.
