Prepare database for creating initial disease extent
Add a view named admin_unit_simplified_global_view, for use as a GeoServer layer (rather than having to define a view at the GeoServer level).
Update mappings between healthmap_country and country.
Change location.passed_qc_stage to a boolean column has_passed_qc (with subsequent code and test data changes).

Add fields to Location table: admin_unit_global_gaul_code, admin_unit_tropical_gaul_code.
Populate these fields by DataAcquisition as a "post-QC process". Use the PostGIS function ST_INTERSECTS because doing it in the Java used an extra 1Gb of RAM.
Remove geom field from the AdminUnitGlobalOrTropical entity as it is not used in the Java (and is much more memory hungry than the simplified geom).
Fix bug whereby locations could be duplicated if they were changed (i.e. snapped) as a result of QC stage 2 or 3.
Ensure that snapped points are rounded to 5 decimal places.
Add code to generate an initial disease extent. Some testing still to do.
Add disease extent and associated columns to the test data.
Add admin_unit_disease_extent_class.occurrence_count column that contains how many disease occurrences gave rise to each extent class.
Split out AbstractSpringIntegrationTests into AbstractCommonSpringIntegrationTests and AbstractDataAcquisitionSpringIntegrationTests.
Added integration test for Disease Extent.
Add tests.
When assigning GAUL codes to locations, only search admin 0's if the location is a country.
Add table of admin units. When row is clicked, the admin unit is selected
