Finished the support for SimRa dataset (Closes #107):
The app version is now included as a field inside the created document
The geo-data points now contain references to the header documents.
Refactored the main dataset support function (now it does not create the documents inside the DB itself, the subfunctions need to do it. Change due to some multi stages for document creation (for SimRa we need to create headers first, get their IDs and then the datapoints)
