The number of levels is the depth of the deepest child reachable from some parent at level 0. It implements a layout technique as described by K. Sugiyama, S. Tagawa, and M. Toda. in "Methods for visual understanding of hierarchical systems", IEEE Transactions on Systems, Man and Cybernetics, SMC-11(2):109-125, Feb. 1981. <p>There have been a few modifications made, however. The crossings function is changed as it was non-linear in time complexity. Furthermore, we don't have any interconnection matrices for each level, instead we just have one big interconnection matrix for the whole graph and a int[][] array which stores the vertices present in each level.<P><P><DL><DT><B>Version:</B></DT> <DD>1.0 - 24 Apr 2003 - Initial version (Ashraf M.
