Adelchi,
Actually, the person recognized wrote the original code for the algorithm and
he has had other contributors over time that have made several improvements.
The code I have is not verbatim from his package as it has been adapted for our
purposes, but he is still the originator of the approach and I am certain he
and others would recognize the code as being clearly deriviative. I have
retained some of the same function names or near derivatives of those names. My
coding style is different but that has not changed the basic logic.
With regard to licensing, we both use MIT, which I strongly prefer. The GPL-2
and GPL-3 licenses are apparently sufficiently ambiguous in the legal community
that some companies avoid them.
