* @class vtkHyperTreeGridNonOrientedMooreSuperCursor
* @brief Objects for traversal a HyperTreeGrid.
*
* JB A REVOIR
* Objects that can perform depth traversal of a hyper tree grid,
* take into account more parameters (related to the grid structure) than
* the compact hyper tree cursor implemented in vtkHyperTree can.
* This is an abstract class.
* Cursors are created by the HyperTreeGrid implementation.
*
* @sa
* vtkHyperTreeCursor vtkHyperTree vtkHyperTreeGrid
*
* This supercursor allows to visit all neighbors including diagonal ones.
*
* @par Thanks:
* This class was written by Guenole Harel and Jacques-Bernard Lekien, 2014.
* This class was re-written by Philippe Pebay, 2016.
* This class was re-written and optimized by Jacques-Bernard Lekien,
* Guenole Harel and Jerome Dubois, 2018.
