jigsaw puzzle helper

Basic idea is to make an andoroid app that can

1. Take image / photo

2. then suggest whatever pieces to next neighboring pieces.

1. I could find some code already built but slightly different approch.

2. so changed the to work for our purpose in python, but it was not fully functional.

3. so tried this and that of solution in core imaging feature and later tried use some ML model freelly provided.

4. better but not great, been trying to create web page that shows the progress and ideas here.

5. but gotten busy for busness acquisition. that's another thread.

6. hope some day I'll post all the effort here or under tkprof.com not sure.
