+	  New Feature: Now we can draw lines into the map.
+	  TODO: The lines have no attributes objektart, user_id, timestamp or
+	  somethings else but the_geom which we need for WSPLGEN calculation.
+
+	* webflys/src/main/webapp/pages/karte.js: New control elements in OL map to
+	  draw lines, save them via WFS-T into PostGIS database and navigating
+	  around.
