Sanitizer

[omid]

What do you think of adding sanitization to this lib?
Validation and Sanitization are so similar in everything, except how they handle the issue.

I actually can clone this nice library and convert it to a sanitization library, but generally, I think it's better to have them in one place and if people want to use both, it will be more performant, I guess.

(Then garde will not be a good name 🙈, but who cares!)
