This repo currently has no license which will unfortunately prevent the community from exploring and adopting any of it. Given its potential importance to advancing the field, it seems this was an accidental oversight and not your intent. Kindly consider accepting this pull request which will add a standard open-source license or, alternatively, adding a license of your choosing.

"When you make a creative work (which includes code), the work is under exclusive copyright by default. Unless you include a license that specifies otherwise, nobody else can copy, distribute, or modify your work without being at risk of take-downs, shake-downs, or litigation. Once the work has other contributors (each a copyright holder), “nobody” starts including you."
