Implement City Growth algorithm

[davidomarf]

Propossed implementation

• Create a terrain with a river and some resource clusters.
• Create a city center at the sides of the river.
• Make it grow by “pursuing” resources in the terrain.

Assumptions

(These will be corrected in further development versions)

• Terrain is completely flat.
• River doesn’t have a flow direction.
• River’s influence on city is just it’s City Core location.
• City core always stablishes on one point of the river.
• City core is perfectly round.
• Resources are the same. There is no variety.

Possible Solution

Already implemented in js, look at https://github.com/davidomarf/generative/blob/master/spatial/sketch.js

Steps to Reproduce (for bugs)

Implement algorithm and use libdaque API to visualize it in ViaRE.
