//! `map_model` describes the world where simulations occur. Importing a map from OSM partly happens
//! in `convert_osm` and here.
//!
//! Helpful terminology:
//! - ch = contraction hierarchy, for speeding up pathfinding
//! - degenerate intersection = only has 2 roads connected, so why is it an intersection at all?
//! - lc = lane-change (which is modelled very strangely: <https://a-b-street.github.io/docs/tech/trafficsim/discrete_event/index.html#lane-changing>)
//! - ltr = left-to-right, the order of lanes for a road
//! - osm = OpenStreetMap
//!
//! Map objects are usually abbreviated in method names:
//! - a = area
//! - b = building
//! - tr = transit route
//! - ts = transit stop
//! - i = intersection
//! - l = lane
//! - pl = parking lot
//! - r = road
//! - ss = stop sign
//! - t = turn
//! - ts = traffic signal
