Show2
Trait for Show for a product of 2 logical elements. This trait is implemented directly by the type in question, unlike the corresponding Show2T trait which externally acts on an object of the specified type to create its String representations. For your own types it is better to inherit from Show2 and then use Show2ElemT or Persist2ElemT to create the type class instance for ShowT. The Show2ElemT or Persist2Elem class will delegate to Show2 for some of its methods. It is better to use Show2 to override toString method than delegating the toString override to a Show2T instance.
