/**
 * Represents a rectangular geographical area on a map.
 *
 * @example
 * ```js
 * const corner1 = new LatLng(40.712, -74.227),
 * corner2 = new LatLng(40.774, -74.125),
 * bounds = new LatLngBounds(corner1, corner2);
 * ```
 *
 * All Leaflet methods that accept LatLngBounds objects also accept them in a simple Array form (unless noted
 * otherwise), so the bounds example above can be passed like this:
 *
 * ```js
 * map.fitBounds([
 * 	[40.712, -74.227],
 * 	[40.774, -74.125]
 * ]);
 * ```
 *
 * Caution: if the area crosses the antimeridian (often confused with the International Date Line), you must specify
 * corners _outside_ the [-180, 180] degrees longitude range.
 *
 * Note that `LatLngBounds` does not inherit from Leaflet's `Class` object, which means new classes can't inherit
 * from it, and new methods can't be added to it with the `include` function.
