 * @class   vtkGenericCell
 * @brief   provides thread-safe access to cells
 *
 * vtkGenericCell is a class that provides access to concrete types of cells.
 * It's main purpose is to allow thread-safe access to cells, supporting
 * the vtkDataSet::GetCell(vtkGenericCell *) method. vtkGenericCell acts
 * like any type of cell, it just dereferences an internal representation.
 * The SetCellType() methods use \#define constants; these are defined in
 * the file vtkCellType.h.
