Provenance to output file
As Hdf5 is more widely adopted, reading provenance information (branch and commit related to generation of data fields) is less immediate than opening the Info.xml file and inspecting it. Some possibilities would be:
- Add brief documentation and/or utilities on how to use h5dump to read information more easily
- Add provenance information to output file (branch and commit ID mainly, or and tags for wider community who may not be updating quite as regularly)
