/**
 * @class   vtkSMPContourGridManyPieces
 * @brief   a subclass of vtkContourGrid that works in parallel
 * vtkSMPContourGridManyPieces performs the same functionaliy as vtkContourGrid but does
 * it using multiple threads. This filter generates a multi-block of vtkPolyData. It
 * will generate a relatively large number of pieces - the number is dependent on
 * the input size and number of threads available. See vtkSMPContourGrid is you are
 * interested in a filter that merges the piece. This will probably be merged with
 * vtkContourGrid in the future.
