+	ISSUE215: Rows will not be merged to one Single Row if their values are identical.
+
+	* src/main/java/de/intevation/gnv/exports/ODVExport.java (writeData): 
+	  Replaced the StringArray using as Key against the new Class StringArrayKey.
+	  This was nessesarry tp detect Rows with same Values joining them to one
+	  Row.
+	* src/main/java/de/intevation/gnv/exports/StringArrayKey.java (StringArrayKey): 
+	  Added new Class for representing the Key of an StringArray not using the 
+	  Hash of the Array but using the hash of the values which are stored in 
+	  the Array.
