Abstract methods
Must be implemented by the user of Magnolia to construct a
typeclass for case class T
using the provided type info.
E.g. if we are deriving Show[T]
typeclasses, and T
is a case class Foo(...)
, we need to constuct Show[Foo]
.

This method is called 'join' because typically it will join together the typeclasses for all the parameters of the case class, into a single typeclass for the case class itself. The field CaseClass.params can provide useful information for doing this.
