This trait provides an Ordering instance for an enumeration as well
as functions which use that order. It works by extending the companion
object of the enumeration class.
@enum class Color {
Red
Blue
Yellow
}
object Color extends Ordered[Color]
This enables the following functions (and more).
Red < Blue // true
Blue.next
Color.next(Blue) // yellow
Yellow >= Yellow // true
Color.first // Red
Color.last // Yellow
