* @class vtkDataSetGhostGenerator

* 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.
