Software and documentation for model-ouput components of AAS-4347

The configuration of the East-Antarctic Atlantis model included several pages of documentation from SOKI (the Southern Ocean Knowledge and Information wiki, hosted at soki.aq in 2019). There is also an associated software package angstroms was used to couple Atlantis models to Regional Ocean Model System (ROMS). The documentation pages have been archived in PDF and WORD format here in 11 separate documents. The software package is included as an archive of the Australian Antarctic Division github repository as at 2019-07-22 with commit '2b7b10e86963195df049ded6ca842255b2335de1'. https://github.com/AustralianAntarcticDivision/angstroms
