* @class vtkExtractRectilinearGrid
* @brief Extract a sub grid (VOI) from the structured rectilinear dataset.
*
* vtkExtractRectilinearGrid rounds out the set of filters that extract
* a subgrid out of a larger structured data set. RIght now, this filter
* only supports extracting a VOI. In the future, it might support
* strides like the vtkExtract grid filter.
