initial commit: basic library framework
This first commit includes the LICENSE and the .gitignore in addition to the beginnings of the zlua (name tbd) library. At this stage src/zlua.zig contains a very basic wrapper around the Lua C API. The goal is to expose every function in a Zig fashion. The build.zig script contains a single entry point `zig build test` to run tests. The intended use of this library will be to include in other projects and link as a package/library.
