Implementation of the Strip algorithm. It is described in:

Ben Shneiderman and Martin Wattenberg. Ordered and quantum treemaps. Information Visualization, 2001. Infovis 2001. IEEE Symposium on pages 73-78, 2001. ISSN 1522-404X.

Complexity: O(sqrt(n)) average, O(n) worse case, where n is the number of nodes in the tree.
