Confie module maintains validation codes.

It provides different drivers to make and verify code:

• Local: send code to output(default to os.Stderr)
• Sms: send code via specific communication operators
• Email: send code via email

And two routes:

• get /confie?type=sms&address=13600008888, with cookie confie=uuid
• confie middleware, check code value in query type=sms&code=123456

Special thanks to @Fenny for naming this module.
