+
+	Refactored version of "Berechnung 4"
+
+	* src/main/java/de/intevation/flys/artifacts/model/Segment.java:
+	  Added instance fields for a reference point (= location of gauge)
+	  and backup of values (needed for naming).
+
+	* src/main/java/de/intevation/flys/artifacts/model/WQCKms.java:
+	  Added a constructor to be created from a WQKms. This is helpful
+	  if a WQKms is replaced by a back jump correction.
+
+	* src/main/java/de/intevation/flys/artifacts/model/Calculation4.java:
+	  New. Outfactored version of "W bei ungleichmaessigen Abflusslaengsschnitt".
+	  Much cleaner now and it should have a better handling of the corner
+	  cases.
+
+	* src/main/java/de/intevation/flys/artifacts/model/WstValueTable.java:
+	  Removed the linear interpolation stuff. It is now in Linear. Removed
+	  the LinearRemap interpolation method because it is not needed any
+	  longer. Added a method to interpolate a given km with a given
+	  function.
+
+	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java:
+	  Removed the old calc 4 and used the new one.
+
+	* src/main/java/de/intevation/flys/artifacts/math/LinearRemap.java:
+	  Deleted. Not needed any longer.
+
+	* src/main/java/de/intevation/flys/artifacts/math/Function.java:
+	  New. Interface for a uni-variate real function.
+
+	* src/main/java/de/intevation/flys/artifacts/math/Identity.java:
+	  New. Implements Function with f(x) = x
+
+	* src/main/java/de/intevation/flys/artifacts/math/Linear.java:
+	  New. Implements Function with f(x) = m*x + b
+
+	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java:
+	  Factored some stuff out to DoubleUtil. Removed some dead code.
+	  Does some rounding correct.
+
+	* src/main/java/de/intevation/flys/utils/DoubleUtil.java: New.
+	  Centralized utils surrounding common double operations.
+
+	* src/main/java/de/intevation/flys/exports/ChartInfoGenerator.java:
+	  Removed superfluous imports.
