 * @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.
