Supertrait for typeclasses that enable the be defined matcher syntax.
A Definition[T] provides access to the "definition nature" of type S in such
a way that be defined matcher syntax can be used with type T. A T
can be any type for which the concept of being defined makes sense, such as scala.Option. ScalaTest provides
implicit implementation for scala.Option. You can enable the be defined matcher syntax on your own
type U by defining a Definition[U] for the type and making it available implicitly.
ScalaTest provides an implicit Definition instance for scala.Option,
arbitary object with isDefined() or isDefined in the Definition companion object.
