* @class vtkHyperTreeGridToUnstructuredGrid
* @brief Convert hyper tree grid to
* unstructured grid.
*
JB Primal mesh
* Make explicit all leaves of a hyper tree grid by converting them to cells
* of an unstructured grid.
* Produces segments in 1D, rectangles in 2D, right hexahedra in 3D.
* NB: The output will contain superimposed inter-element boundaries and pending
* nodes as a result of T-junctions.
