String validation and sanitization dub lib

[aberba via Digitalmars-d]

I might be working on a project which might require a lot of 
string pathern validation and sanitization. Planning to make that 
into a dub package.

Currently, I am not very familiar with regex in D but I did regex 
stuff long ago. So if anyone has code or interest for something 
like that, I would rather contribute to it.

My inspiration comes from https://github.com/chriso/validator.js
