A port of microKanren, a minimal logic programming engine, to Lua.

Based on Jason Hemann and Daniel P. Friedman's "microKanren: A Minimal Functional Core for Relational Programming".

The paper's implementation does not appear to specify a license. I am releasing this under the ISC license, but will change it at the papers' authors' request.

Note that this is extremely alpha code! I wrote it while working through that paper. Don't consider it robust, don't use it in production yet, etc. The example uses from the paper don't even give full branch coverage.
