Added citizens to our game! They are tracked individually, belongs to a family and they tweet (in-game tweet I mean)!. Basic menu and the ability to spawn residential zones and industrial zones has also been done. Once the residential buildings are constructed new families will start moving as long as a slot for new family is available. A basic economy system has also been added so each building has its own upkeep per cost and they also pay taxes which is the main source of income. Buildings also require electricity to work properly.
