Improvements to exporting pds4 files from ISIS3 cubes
isis2pds with pdsversion=pds4 will produce more pds4-compliant output. See documentation for more details.
We (Jeannie, Kristin, Jesse) updated the code used to export ISIS3 cubes to pds4 images and xml headers.
The generated pds4 images and associated headers will now open with pds4viewer with minor user modifications (explained in the isis2pds documentation -- these are details we cannot predict, so they can't be automatically exported.)
These changes now need to be checked into ISIS3.
