Document how to share schema validations about dry-validation

[solnic]

There's no API for it yet, I'll try to add it in the upcoming, big 0.7.0 release, or 0.7.1

I'm going to make it possible to simply write key(:address, AddressSchema). Sounds good?

[timriley]

Would you expect AddressSchema to be a Schema class or instance? Just wondering about how you'd go about composing schemas that need to be instantiated with dependencies provided for their own custom predicate methods to work...

@timriley I want to see if it's feasible to always use nested schemas, so that under each key you have a schema object and you can nest them, then schema rules would become a hash of nested schemas

[solnic]

immediate update: we can't assume a nested schema when using key syntax because it could be either a nested hash or a flat value. So I'm wondering about either key(:foo, schema: true) { .. } or schema(:foo) { .. }. Hmm
