[kandelvijaya]

Thanks for contributing to the swift community.

As an author of my own implementation of Diff based on Heckel's algorithm I wanted to know if you did try the comparision with implementation based on Heckel's algo?

Im working on this www.github.com/kandelvijaya/fastdiff while there are few others around. The next immediate one is DeepDiff (should be).
