Very nice API. I do have a question, and not to be dismissive, but is there a strong reason to use Forg over Validatejs. The APIs are pretty similar so I don't know what I would choose Forg over ValidateJS.

Some things to address:

* Typescript definitions

* ES/6 import documentation

* There are a lot of tiny typos in the readme, it would make sense to spell check that.

Thanks for the contribution.
