// .NAME vtkBoxLayoutStrategy - a tree map layout that puts vertices in square-ish boxes
//
// .SECTION Description
// vtkBoxLayoutStrategy recursively partitions the space for children vertices
// in a tree-map into square regions (or regions very close to a square).
//
// .SECTION Thanks
// Thanks to Brian Wylie from Sandia National Laboratories for creating this class.
