9.  def extract[A](implicit formats: Formats, mf: Manifest[A]): A

   Extract a value from a JSON.

   Extract a value from a JSON.

   Value can be:

   • case class
   • primitive (String, Boolean, Date, etc.)
   • supported collection type (List, Seq, Map[String, _], Set)
   • any type which has a configured custom deserializer

   Example:

   case class Person(name: String)
   JObject(JField("name", JString("joe")) :: Nil).extract[Person] == Person("joe")
   

10.  def extractOpt[A](implicit formats: Formats, mf: Manifest[A]): Option[A]
