I think the original classes had Array as a single-dimensional array
only, Array2 as a 2-dimensional array, and ArrayN providing
N-dimensional arrays.  But then at some point, Array was extended to
handle all dimensions.  So I think it is good to get rid of ArrayN.
Thanks for doing this job.

OK.

I suppose the funtionality of Array2 might be absorbed by Array.  For
things that only make sense for 2-d arrays (transpose, hermitian,
etc.) we would simply need checks to ensure that the object actually
has exactly 2 dimensions and otherwise throw an error.  Would that work?
