surface to volume possible bug for non-surfacewta?

[kendrickkay]

Here there may be a Python port bug.

Specifically, examples_nsdmapdata.py has an example of how to use the crazy "mapsurfacetovolume" functionality. See attached screenshot.

For the case of interptype='surfacewta', i think the example works.

However, when interptype is changed to [] (or whatever the "default" is), i think the example fails in the sense that the output is weirdly rotated/permuted. We saw this on our end.

@iancharest - can you try the example snippet and see whether the results are consistent across surfacewta and not?
