+// .NAME vtkCellType - define types of cells
+// .SECTION Description
+// vtkCellType defines the allowable cell types in the visualization
+// library (vtk). In vtk, datasets consist of collections of cells.
+// Different datasets consist of different cell types. The cells may be
+// explicitly represented (as in vtkPolyData), or may be implicit to the
+// data type (as in vtkStructuredPoints).
+
+#ifndef __vtkCellType_h
+#define __vtkCellType_h
+
+// To add a new cell type, define a new integer type flag here, then
+// create a subclass of vtkCell to implement the proper behavior. You
+// may have to modify the following methods: vtkDataSet (and subclasses)
+// GetCell() and vtkGenericCell::SetCellType(). Also, to do the job right,
+// you'll also have to modify some filters (vtkGeometryFilter...) and
+// regression tests (example scripts) to reflect the new cell addition.
+// Also, make sure to update vtkCellTypesStrings in vtkCellTypes.cxx.
+
+// .SECTION Caveats
+// An unstructured grid stores the types of its cells as a
+// unsigned char array. Therefore, the maximum encoding number for a cell type
+// is 255.

+// This program translates a newpop netCDF data file to dual-grid legacy, ascii VTK format
+// The variables that have time dim are automatically written.
+//
+// Assume all variables are of interest.
+// Assume variable data type is double.
+// Assume variable dims are (Time, nCells|nVertices, nVertLevels|nVertLevelsP1, [nTracers])
+// Assume no more than 100 vars each for cell and point data
+// Does not deal with edge data.
+// Doubles converted to floats in .vtk files follow these rules:
+// if a NaN, then become -FLT_MAX.
+// if positive infinity, then become FLT_MAX
+// if negative infinity, then become -FLT_MAX
+// if smaller than a float, then become 0.
+// if not zero, but between -FLT_MIN and FLT_MIN make -FLT_MIN or FLT_MIN
+// if outside of -FLT_MAX and FLT_MAX make -FLT_MAX or FLT_MAX

+// .NAME vtkCellType - define types of cells
+// .SECTION Description
+// vtkCellType defines the allowable cell types in the visualization
+// library (vtk). In vtk, datasets consist of collections of cells.
+// Different datasets consist of different cell types. The cells may be
+// explicitly represented (as in vtkPolyData), or may be implicit to the
+// data type (as in vtkStructuredPoints).
+
+#ifndef __vtkCellType_h
+#define __vtkCellType_h
+
+// To add a new cell type, define a new integer type flag here, then
+// create a subclass of vtkCell to implement the proper behavior. You
+// may have to modify the following methods: vtkDataSet (and subclasses)
+// GetCell() and vtkGenericCell::SetCellType(). Also, to do the job right,
+// you'll also have to modify some filters (vtkGeometryFilter...) and
+// regression tests (example scripts) to reflect the new cell addition.
+// Also, make sure to update vtkCellTypesStrings in vtkCellTypes.cxx.
+
+// .SECTION Caveats
+// An unstructured grid stores the types of its cells as a
+// unsigned char array. Therefore, the maximum encoding number for a cell type
+// is 255.
