Ported to Java from C code from http://www8.cs.umu.se/kurser/TDBAfl/VT06/algorithms/WEBSITE/IMPLEMEN/TURN/IMPLEMEN.HTM May only be used for non-commercial purposes. Implementation of "An Efficiently Computable Metric for Comparing Polygonal Shapes," by Arkin, Chew, Huttenlocher, Kedem, and Mitchel (undated). This expands a little on the cited reference to achieve O(n) space and O(mn log n) run time. This could be improved to O(min m,n) and O(mn log min m,n) by selecting the smallest of the 2 polys to create the initial event heap. See init_events(). Variable names match the article.
