Multirun DB Setup currently doesn't check whether training data should be used

May just need an extra test, ie:

		// Detect if data available; set to testing data if not
		Collection<File> testList = FileUtils.listFiles(new File(Parameters.getInputDirectoryInitialPopulations()), new String[]{"csv"}, false);
		if (testList.size()==0)
			Parameters.setTrainingFlag(true);
