+	Fix setting of kilometer for profile (not yet waterlevel) of cross section
+	diagram.
+
+	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java:
+	  (getCrossSectionData): Respect corss_section.km data; do naive linear
+	  search for profile data for this km.
+
+	* src/main/java/de/intevation/flys/artifacts/model/CrossSectionFacet.java:
+	  Declare a ComputeType.
+
+	* src/main/java/de/intevation/flys/artifacts/states/WaterlevelState.java:
+	  Implement computeFeed.
