After several months of intermittent tinkering with some different use
cases and file formats, I've settled on what I think should be a good
API for surface-based images. I've changed the name to CoordinateImage
to reflect that the surfaces are only one source of coordinate arrays,
and much of the work needed to support surfaces would apply equally to
other sources of coordinates.

In particular, there's an abstraction layer of sequences of subsets of
pointsets that is used by CIFTI-2 and MNE's STC format that can be
thought of as a CoordinateAxis.

Please read through the BIAP and let me know what you think!
