/**
* @class vtkExtractGeometry
* @brief extract cells that lie either entirely inside or outside of a specified implicit function
*
*
* vtkExtractGeometry extracts from its input dataset all cells that are either
* completely inside or outside of a specified implicit function. Any type of
* dataset can be input to this filter. On output the filter generates an
* unstructured grid.
*
* To use this filter you must specify an implicit function. You must also
* specify whethter to extract cells laying inside or outside of the implicit
* function. (The inside of an implicit function is the negative values
* region.) An option exists to extract cells that are neither inside or
* outside (i.e., boundary).
*
* A more efficient version of this filter is available for vtkPolyData input.
* See vtkExtractPolyDataGeometry.
