Moon-bignum

This is mostly an example of how to use Moon to export a npm lib. The steps are simple:

1. Create your library as a lib.moon file.

2. Use echo \"module.exports = $(moon compile lib)()\" > lib.js to make a CommonJS lib.

3. Optionally, use ccjs lib.js > lib.min.js to minify.

4. Export it on package.json.

Note: this uses very simple bignum algorithms and isn't very optimized. Division in particular is very slow.
