+	* src/main/java/de/intevation/gnv/statistics/HorizontalProfileVectorStatistics.java:
+	  This is a class to create statistics for horizontal profiles with
+	  vectorial parameters.
+
+	* src/main/java/de/intevation/gnv/state/profile/horizontal/HorizontalProfileMeshVectorOutputState.java:
+	  Added a new method to return an instance of
