Class up your config

" summary

Case Classy provides composable decoders (arrows typed A => Either[DecodeError,B]) that load TypeSafe Config, Java properties and Map[String,String] into Scala case classes, with accumulating error ADT that reports every failure (example: a list of five sealed-shape variants shows indexed errors for each invalid entry). Decoders compose with simple combinators and handle nested paths; Shapeless auto-derivation generates decoders automatically. Core module has no deps, works on JVM and Scala.js, and offers no built-in live reload (redecode manually).
