/**
* Semi-automatic codec derivation.
*
* This object provides helpers for creating [[io.circe.Decoder]] and [[io.circe.ObjectEncoder]]
* instances for case classes, "incomplete" case classes, sealed trait hierarchies, etc.
*
* Typical usage will look like the following:
*
* {{{
* import io.circe._, io.circe.generic.semiauto._
*
* case class Foo(i: Int, p: (String, Double))
*
* object Foo {
* implicit val decodeFoo: Decoder[Foo] = deriveDecoder[Foo]
* implicit val encodeFoo: Encoder.AsObject[Foo] = deriveEncoder[Foo]
* }
* }}}
