Hey @spencersutton, thanks for the contribution, looking good.

One thing thought, I cannot see the internal module export at main index.ts file, did you missed that?

Let me know if something is not clear. Thanks

I did miss adding it to index.ts. I've added that and incorporated your feedback. AugmentedRequired is now used everywhere and is renamed Required in the index.ts.

That's awesome, thanks!

I'll prepare a release tomorrow.
