Intro

 This blog is to discuss my routine pnpoly, e.g.:

1. make suggestions
2. ask questions
3. present your own code

Documentation and code are here:

Various writers have strong opinions about additions, such as that points on the boundary should be handled.  I disagree, for reasons listed in the page linked above.  However, feel free to argue your case here.
