// .NAME vtkGenericCellIterator - iterator used to traverse cells
// .SECTION Description
// This class (and subclasses) are used to iterate over cells. Use it
// only in conjunction with vtkGenericDataSet (i.e., the adaptor framework).
//
// Typical use is:
// <pre>
// vtkGenericDataSet *dataset;
// vtkGenericCellIterator *it = dataset->NewCellIterator(2);
// for (it->Begin(); !it->IsAtEnd(); it->Next());
// {
// spec=it->GetCell();
// }
// </pre>
