Structure

• Main node coordinates the other classes and does some simple drawing.
• CityGen node contains the city generation algorithm. The size of the city can be customized using the segment_count_limit in the inspector for the node.
• PopulationHeatmap node generates the population heatmap that influences the density of the generated city. The noise used for the heatmap can be customized in the inspector for the node.

city_gen.gd can be easily copied out for use in other projects, since its only dependency is the PopulationHeatmap node.
