making lift-json easier

def json[T](serialize: T => JValue, deserialize: JValue => Result[T]): JSON[T] = new JSON[T] {
  def write(t: T) = serialize(t)
  def read(jval: JValue): Result[T] = deserialize(jval)
}

//usage
case class MyClass(i: Int)
implicit val myClassSerializer = json[MyClass](
  serialize = C => i: JValue,
  deserialize = j => ????
)

This is nicer, but I'd still have to do

case class MyClass(i: Int)

val iJsonKey = "i"

implicit val myClassSerializer = json[MyClass](
  serialize = (myClass: MyClass) => (iJsonKey -> myClass.i): JValue
  deserialize = (j: JValue) => field[Int](iJsonKey)(j).map(MyClass(_))
)

There's still the possibility to get this wrong with a stupid mistake, like copying a line and ending up with the wrong string tied to the wrong field. Perhaps something like this that gets the field types from reflection? Presumably that's what other case class serializers do

nothing that sophisticated. I wrote this to help avoid writing the boilerplate of writing new JSON[T] {....}
