[vtkusers] Difference between cells and polygons

[David Goldsmith]

Hi!  In plain English, what is (are) the difference(s) between cells
and polygons?  And if I'm trying to loop over the triangles (are these cells or polygons?) created by vtkDelaunay2D from
numbered points to get the point numbers of each triangle's vertices,
as well as each triangle's neighboring triangle objects, which vtkPolyData method
do I use for each of these tasks?  Thanks!
