Thanks to the suggestion form @k-griffiths, this update:
makes \documentclass[embargoed]{grattan} the default Report.tex document class. Reports have to go through this stage before release, so should be the starting place.
adds detailed comments on how to change \documentclass options.
structures the preamble in a neater/easier to read way.
It also adds longtable to the list of required packages in grattan.cls, as this is used commonly in Grattan reports.
