I'm pretty sure that this means that I have to change the signature
of copyout so that returns MultiArrayImpl rather than  MultiArray. I've
been thinking about doing this for other reasons, and this is the last straw.
The defining point is in multiarray/Accessor.java, but it will have trivial
repercussions wherever there is a definition in an implementing class.
