   * @class   vtkAppendLocationAttributes
   * @brief   add point locations to point data and/or cell centers cell data, respectively
   *
   * vtkAppendLocationAttributes is a filter that takes as input any dataset and
   * optionally adds points as point data and optionally adds cell center locations as
   * cell data in the output. The center of a cell is its parametric center, not necessarily
   * the geometric or bounding box center. Point and cell attributes in the input can optionally
   * be copied to the output.
   *
   * @note
   * Empty cells will have their center set to (0, 0, 0).
