UM Aquo Standard names

{code}
//!! Working draft on how to encode UM Aquo semantics
//!! into netCDF syntax. This will apply to Dutch government
//!! data and model output in netCDF as present in:
//!! OpenEarth: http://opendap.deltares.nl/thredds/catalog/opendap/rijkswaterstaat/waterbase/catalog.html
//!! Matroos : https://opendap-matroos.deltares.nl/thredds/catalog.html (access registration required)
//!! This is an example for in situ salinity data at one location.
//!! The additions related to UM Aquo are indicated with //!!
