  * Main product and version information strings.
  * 
  * --- Changelog
+ * 2.029: Tuned the 2d-graphs which now paints quicker and changes size depending on the
+ * 			surrounding plot window. 
  * 2.028: Tuned the Population to sort only when necessary on calls to getBestN... Added StatisticsDummy.
  * 			Slightly tuned SimpleProblemWrapper to call initProblem of simple problems if available.
  * 2.027: Renamed SetData and SetDataLamarckian from individual datatype interfaces to SetGenotype and SetPhenotype.
