Hi, it's been a while since I release this library and I haven't been compromised with it, I understand that there are many bugs, I'd love to check them all, but I'm really busy at other projects, so I have to apologize and recommend you to fork this project or send me a PR, I'l review it ASAP.

Cheers!
