// .NAME vtkCellIntegrator - Calculates length/area/volume of a cell
// .SECTION Description
// vtkCellIntegrator is a helper class that calculates the
// length/area/volume of a 1D/2D/3D cell. The calculation is exact for
// lines, polylines, triangles, triangle strips, pixels, voxels, convex
// polygons, quads and tetrahedra. All other 3D cells are triangulated
// during volume calculation. In such cases, the result may not be exact.
