+	* src/main/java/de/intevation/flys/artifacts/model/fixings/FixCalculation.java:
+	  Made abstract. Sub classes have to overwrite innerCalculate()
+	  calculate() now figures out the fixings overview and the function
+	  to fit and passes it to innerCalculate()
+
+	* src/main/java/de/intevation/flys/artifacts/model/fixings/FixAnalysisCalculation.java,
+	  src/main/java/de/intevation/flys/artifacts/model/fixings/FixRealizingCalculation.java:
+	  Overrides innerCalculate() now.
