+Version 1: Closest to the original Pixture game.
+           Used till game version 2.1.0
+Version 2: Major biome update introducing tons of new biomes and
+           removing the Desert. Introduced more swamp biomes,
+	   swamp highland, dry land biomes, shrubbery, oak forests,
+	   birch forests,  "technical" ocean/beach biomes,
+	   Underground biome, and much more.
+	   Biome heat/humidity points of existing biomes had to be
+	   completely updated.
+	   Introduced in game version 2.2.0.
