* @class vtkHyperOctreeLimiter
* @brief Limit the tree's depth, averaging data
* from lower level branches into the new leaves at the cut points.
*
* This filter returns a lower resolution copy of its input vtkHyperOctree.
* It does a length/area/volume weighted averaging to obtain data at each
* cut point. Above the cut level, leaf attribute data is simply copied.
