Some of this functionality should maybe be reorganized or incorporated into the importer crate,
but for now, it’s convenient to organize it here.</p>
<p>All of the types and methods here are tied to a single <code>Map</code>. Even if a city is chopped up into
multiple pieces, for now, let’s assume we’re just dealing with one map at a time. That lets us
use the map’s coordinate system, building IDs, etc.</p>
<p>These types form a pipeline:</p>
<ol>
<li>For a given map, find some census data that describes how many people live in different
areas of the city. (CensusArea)</li>
<li>Take the CensusAreas and turn them into individual CensusPersons, by randomly choosing a
specific building on the map as their home, and assigning specific attributes based on the
census data’s distribution.</li>
<li>For each CensusPerson, classify them into a PersonType, then generate a Schedule of
different Activities throughout the day.</li>
<li>Pick specific buildings to visit to satisfy the Schedule.</li>
</ol>
