New authorization gem: know_it_all

Hey guys! I’be been using Pundit for years now to perform authorization
in my applications, but recently I was having trouble providing helpful
error feedback for a mobile developer through the API. Based on that,
I’ve build and released a new gem, heavily inspired in Pundit, but more
flexible in the arguments it accepts and easier to identify the errors
and render them in the API’s response. It could be called
use_case_validator, but that’s a boring name.

Here it is:

I hope it’s helpful to you guys as it was to me. :slight_smile:
