* @class vtkExtractUserDefinedPiece
* @brief Return user specified piece with ghost cells
*
*
* Provided a function that determines which cells are zero-level
* cells ("the piece"), this class outputs the piece with the
* requested number of ghost levels. The only difference between
* this class and the class it is derived from is that the
* zero-level cells are specified by a function you provide,
* instead of determined by dividing up the cells based on cell Id.
