* @class vtkCleanUnstructuredGridCells
* @brief remove duplicate/degenerate cells
*
*
* Merges degenerate cells. Assumes the input grid does not contain duplicate
* points. You may want to run vtkCleanUnstructuredGrid first to assert it. If
* duplicated cells are found they are removed in the output. The filter also
* handles the case, where a cell may contain degenerate nodes (i.e. one and
* the same node is referenced by a cell more than once).
*
* Programmed 2010 by Dominik Szczerba <dominik@itis.ethz.ch>
