Examples aren't compiling on Windows 10.

Oniguruma is regex library written in C. Why not just use Rust's own regex library? So we don't get build errors like that.

Why not just use Rust's own regex library?

see #12

See the new pure-Rust fancy-regex mode introduced in v4.0.0 to avoid this issue!

Still hoping that onig's build will eventually improve but for now fancy-regex is a good option.
