Add ability to send a POST request to WebServiceClient
First draft of running the model from Data Acquisition.
The disease extent sent to the model is now a mapping between GAUL codes and extent class weightings.
Exclude COUNTRY points from the model.
Run the model from the main class.
Add tests.
Add a ModelRun table and use it to store model run details in Data Acquisition.
Fix checkstyle violations
Send the location's QC GAUL code to the model (rather than global/tropical GAUL code). Fix test data accordingly.
Rename "getDiseaseOccurrencesForModelRun" to "getDiseaseOccurrencesForModelRunRequest".
Fix checkstyle violation.
Merge pull request #100 from SEEG-Oxford/156-da-run-model
