Simple Validation Class for JavaScript.
This is really just a collection of common validation functions stuck on an object literal - calling it a class, while accurate, sounds a little more breathy than is deserved.
This is far from complete, and contains mostly string tests (for user input). There's been very little debug and no documentation - if anyone has anything to add (or modify), please feel free to fork and I'll pull anything that looks handy. These functions are very common but I've yet to find a comprehensive collection.
