First iteration's World Generator finishing

Abstract joining points for the DefaultGenProgram and Geographies through the Generation Rule Set and its GenAlgoBase extensions Flow (River) and Add (Cave) getting completed - yes, soon the Geography Generation meets its finalized first version. Some of the many parameters I want to cut out into a configuration file. Thus I can get onto the next level of development: wildlife and moving units' display system basics for'em. :-) (Check the map's light blue lines of the rivers on the shot... the GenAlgoFlow has created'em...)
