Tutorial: Map Generator - Randomness

This is the third part of the map generator tutorial. The previous part can be found here, and should be completed before trying this part of the tutorial. In the two previous parts you learned how to create overlays and combined them with logical operators, use algorithms and how to transform them. These ingredients do allow you to build some basic maps already as seen in the previous exercise, but we need one more aspect of the map generator to make landscape really interesting. That aspect is randomness and is treated in this part of the tutorial. There are two ways randomness is introduced into maps, these are through algorithms and through a single transformation called turbulence.
