Get the edit path

[whj0401]

Thanks for your great work. It is extremely efficient.
I am trying to use this tool in my situation. A problem is that I need the detailed edit path, including the nodes and edges being inserted, substituted, and deleted (the deleted node is not necessary due to lemma 3.1). It seems current implementation provides the final distance only.

Could you provide some hints on how to achieve this?
Thank you in advance.
