/**
 * @class   vtkRemovePolyData
 * @brief   Removes vtkPolyData cells from an input vtkPolyData
 *
 * vtkRemovePolyData is a filter that removes cells from an input vtkPolyData
 * (defined in the first input #0), and produces an output vtkPolyData (which
 * may be empty).  The cells to remove are specified in the following ways:
 * 1) a list of cell ids can be provided; 2) a list of point ids can be
 * provided - any cell using one or more of the points indicated is removed;
 * and 3) one or more additional vtkPolyData inputs can be provided -
 * matching cells are deleted. These three methods can be used in combination
 * if desired. Point and cell attribute data associated with the remaining
 * cells are copied to the output.
 *
 * @warning
 * The filter vtkAppendPolyData enables appending multiple input
 * vtkPolyData's together. So vtkAppendPolyData functions as an
 * approximate inverse operation to vtkRemovePolyData.
 *
 * @warning
 * The output point type is the same as the (first) input point type.
