TODO

• Support enums
• Cascade coercion so that you don't have to specify it on every attribute
  • This could be a bad idea
  • I want to be able to coerce json, not necessarily coerce ints to string
  • What I really want is for json parsing to turn fields into the string value when the parent is coercing
  • this is probably why I originally had object pulling the raw value from JSON::Any when passing to coerce instead of passing the json
• Allow specifying the path on the object validation
  • When checking password confirmation, the path of the error should point towards it
