trait IdentityFlatten[F[+_]] extends AssociativeFlatten[F]
IdentityFlatten
described a type that can be "flattened" in an
associative way and has an identity element with respect to that operation.
For example, with a list we can always vacuously add a layer by wrapping a
list in another list constructor and flattening the resulting list always
returns the original list unchanged.
