* @class vtkSliceAndDiceLayoutStrategy
* @brief a horizontal and vertical slicing tree map layout

* Lays out a tree-map alternating between horizontal and vertical slices,
* taking into account the relative size of each vertex.

* @par Thanks:
* Slice and dice algorithm comes from:
* Shneiderman, B. 1992. Tree visualization with tree-maps: 2-d space-filling approach.
