Add is_validated to disease_occurrence table: test data reflects assignment of true where occurrence's location has_passed_qc and false if not passed. This will be changed when formula to identify points for validation is implemented.
Save updated weightings to DB - only for the occurrences with a changed value, instead of iterating over all occurrences.
Replace configuration service properties file containing lastRetrievalDate with lastModelRunPrepDate on each DiseaseGroup
Reorganise data: location resolution weighting added to test data txt file; disease group weighting moved from update command in data.sql to test data text file; remove default value for disease group last model run prep date
Update validation weighting and final weighting of all DiseaseOccurrencesForModelRun
Shift weighting from [-1, 1] to [0,1]
Fix date time format for Travis
