Adding procedures that will allow read/write of raw data in HDF5 format. No Nexus file definition has been settled upon yet, so I made up my own for testing, simply converting what was present in the VAX file header. Simple read/write operations are functional, but no full scale testing.
Transmission calculation is partially broken as there are no file suffixes anymore.
Otherwise, a good starting point for the HDF5/Nexus of the future.
