Examples in Intermediate Rails -> Custom Validations can be done w/o custom validations about textbook-curriculum HOT 3 CLOSED

For the custom method, we could use the Luhn algorithm for validating credit cards, but that might require too much contextual overhead.

For tomorrow (C6) I say we just roll with it, we can come back to this for C7 if we have time.

Sure we could use a more complicated example to show a custom validation
and we could do my custom validation with the built-in tools, but the point
is simply to show how a custom validation can be written and used without
having to learn another algorithm as well, for the initial example.

Luhn makes a very good use-case for a followup example or homework however.

That's a good thing to add for C7.
