##
# Casts `env.curation_concern` from a `ActiveFedora::Base` model to a
# `Valkyrie::Resource` resource.
#
# If the curation concern is not an `ActiveFedora::Base` this is a
# no-op.
#
# This can be used in conjunction with `ValkyrieToActiveFedora` to create a
# vertical boundary in the actor stack between actors that deal with
# `ActiveFedora` models and those that work on `Valkyrie::Resource` objects.
#
# @example defining a stack using both ActiveFedora and Valkyrie actors
# stack = ActionDispatch::MiddlewareStack.new.tap do |middleware|
# middleware.use ActorThatUsesActiveFedora
# middleware.use AnotherActorThatUsesActiveFedora
# middleware.use ValkyrieToActiveFedora # casts on the way up
# middleware.use ActiveFedoraToValkyrie # casts on the way down
# middleware.use ActorThatUsesValkyrie
# middleware.use AnotherActorThatUsesValkyrie
# end
#
# actor = stack.build(Hyrax::Actors::Terminator.new)
#
# @see ValkyrieToActiveFedora
