/**
* @class vtkExpandMarkedElements
* @brief expands marked elements to including adjacent elements.
*
* vtkExpandMarkedElements is intended to expand selected cells to
* grow to include adjacent cells. The filter works across all blocks in a
* composite dataset and across all ranks. Besides cells, the filter can be used
* to expand selected points instead in which case adjacent points are defined
* as points on any cell that has the source point as one of its points.
*
* The selected cells (or points) are indicated by a `vtkSignedCharArray` on
* cell-data (or point-data). The array can be selected by using
* `SetInputArrayToProcess(0, 0, 0,...)` (see
* vtkAlgorithm::SetInputArrayToProcess).
*
* Currently, the filter only supports expanding marked elements for cells and
* points.
