 gem for rails apps to generates string ids with a prefix, followed by a [nanoid](https://zelark.github.io/nano-id-cc/). similar to the ids you see in stripe's api. also able to lookup any record by id, similar to rails' globalid. there's an [introductory blog post](https://schpet.com/note/cool-id) explaining why i made this.

-this approach allows you to keep your primary key as an auto-incrementing integer while still benefiting from CoolId's functionality. it's particularly useful when you want to expose a public identifier that's separate from your internal primary key.
