// .NAME vtkThickenLayeredCells
// .SECTION Description
// vtkThickenLayeredCells is a filter that thickens cells processing them in
// layers (highest to lowest) using average thickeness. Both thickness and
// layers information is expected as cell-data in the input dataset.
// Currently this filter only supports wedges.
