// .NAME vtkDataSetToRectilinearGrid - Extract histogram data (binned values) from any 
// dataset
// .SECTION Description
// vtkDataSetToRectilinearGrid accepts any vtkDataSet as input and produces a
// vtkPolyData containing histogram data as output.  The output vtkPolyData
// will have contain a vtkDoubleArray named "bin_extents" which contains
// the boundaries between each histogram bin, and a vtkUnsignedLongArray
// named "bin_values" which will contain the value for each bin.
