WIP: Describe array order terminology in 2D, 2D+c, 3D, 3D+c arrays

Still working on it, but just thought I'd check this in so that we can tag it as 0.11.
Could you make all of the dimensions the same (or at least the first and last) so that there are the same number of iterations through the loops to make it a more apples-to-apples comparison.
