// .NAME vtkDataSetGhostGenerator.h -- Base class for ghost data generators
//
// .SECTION Description
// An abstract class that provides common functionality and implements an
// interface for all ghost data generators. Ghost data generators accept as
// input a partitioned data-set, defined by a vtkMultiBlockDataSet, where each
// block corresponds to a partition. The output consists of vtkMultiBlockDataSet
// where each block holds the corresponding ghosted data-set. For more details,
// see concrete implementations.
//
