/**
* @class vtkExtractUnstructuredGrid
* @brief extract subset of unstructured grid geometry
*
* vtkExtractUnstructuredGrid is a general-purpose filter to
* extract geometry (and associated data) from an unstructured grid
* dataset. The extraction process is controlled by specifying a range
* of point ids, cell ids, or a bounding box (referred to as "Extent").
* Those cells laying within these regions are sent to the output.
* The user has the choice of merging coincident points (Merging is on)
* or using the original point set (Merging is off).
*
* @warning
* If merging is off, the input points are copied through to the
* output. This means unused points may be present in the output data.
* If merging is on, then coincident points with different point attribute
* values are merged.
