Tested platform: Kagiso only since it is only a comment block change. If it works in one machine, it should work in all, I hope. Still need to check the parallel build on copper.
one-indexed. Changed the names of some constants to be more consistent. Tested on juniper, smirom, and copper.
Also cleaned up one old API routine in H5Ppublic that isn't used. Tested on smirom and kagiso. More testing to follow.
