Changes for version 0.005 - 2017-03-23
- Use cross product of sets instead of Regexp::Genex. A crash happened inside Regexp::Genex when I integrated this module into a larger package. unexpected token '(' during '' at /opt/perl-5.20.2/lib/site_perl/5.20.3/Regexp/Genex.pm line 455. I don't know what caused it, but it's scared me off Regexp::Genex for now. I think the new code is cleaner anyway.
