Exercise 4 - Cities I

Create cities in our map that generate passengers

Home | Exercise 3 - Connections I | Exercise 5 - Transport I

Summary

Let's create cities in our maps! In this first stage, we want a city to be positioned in just on x,y coordinate in our map! These cities will have a random population (> 100) and will generate each turn some passengers to travel between cities in our world! The ratio will be changed later on, but at the moment we can agree on 0.2% of city population per turn.

| CITY SIZE  | 1 turn | 5 turns | 10 turns |
|------------|--------|---------|----------|
|      100   |  0 PAX |   0 PAX |    1 PAX |
|      500   |  1 PAX |   5 PAX |   10 PAX |
|     1000   |  2 PAX |  10 PAX |   20 PAX |
|     2500   |  5 PAX |  25 PAX |   50 PAX |

We also want to avoid having 2 cities to close to each other, so we'll need to put some rule to avoid cities with a distance lower than 6

I would recommend putting all these variables like percentage of PAX per turn or min distance between cities to be stored in a configuration, so it can be changed easily later on
