+	Use the column cache to establish a consistent index scheme.
+	TODO: Store the index values in the created QWDs.
+
+	* src/main/java/de/intevation/flys/artifacts/model/fixings/FixCalculation.java:
+	  doFitting() fetches the columns from column cache, too.
+
+	* src/main/java/de/intevation/flys/artifacts/model/fixings/FixAnalysisCalculation.java:
+	  Reuse same column cache from fitting to have the same index scheme.
+
+	* src/main/java/de/intevation/flys/artifacts/model/fixings/FixRealizingCalculation.java:
+	  Adjusted to use the column cache.
