+	  Use improved caching for cross section data. 
+	  !!! This commit needs heavy testing !!!
+
+	* src/main/java/de/intevation/flys/artifacts/services/CrossSectionKMService.java:
+	  Refactored to provide the map to determine the nearest cross section line
+	  neighbors for a given km to the public. This is a bit hackish because
+	  it hhould have its own factory which is then used by this service and 
+	  other parts of the code.
+
+	* src/main/java/de/intevation/flys/artifacts/CrossSectionArtifact.java:
+	  searchCrossSectionLine() now returns a FastCrossSectionLine. To find this
+	  line efficiently it uses the map of the CrossSectionKMService which
+	  already provides a nearest neighbor searching mechanism for cross
+	  section lines. The FastCrossSectionLine is fetched with the
+	  FastCrossSectionLineFactory which uses a cache as described in the
+	  previous commit.
+
+	* src/main/java/de/intevation/flys/exports/CrossSectionGenerator.java
+	  src/main/java/de/intevation/flys/artifacts/WaterLineArtifact.java,
+	  src/main/java/de/intevation/flys/artifacts/model/CrossSectionWaterLineFacet.java,
+	  src/main/java/de/intevation/flys/artifacts/StaticWKmsArtifact.java,
+	  src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: Uses
+	  the FastCrossSectionLine instead of CrossSectionLines now.
+
+	* src/main/java/de/intevation/flys/artifacts/model/FastCrossSectionLine.java:
+	  Added method fetchCrossSectionProfile() to access the point data in
+	  the profile generating compatible way.
+
+	* src/main/java/de/intevation/flys/artifacts/ChartArtifact.java: Removed
+	  superfluous import.
