/*
 * @class Bounds
 * @aka L.Bounds
 *
 * Represents a rectangular area in pixel coordinates.
 *
 * @example
 *
 * ```js
 * var p1 = L.point(10, 10),
 * p2 = L.point(40, 60),
 * bounds = L.bounds(p1, p2);
 * ```
 *
 * All Leaflet methods that accept `Bounds` objects also accept them in a simple Array form (unless noted otherwise), so the bounds example above can be passed like this:
 *
 * ```js
 * otherBounds.intersects([[10, 10], [40, 60]]);
 * ```
 *
 * Note that `Bounds` 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.
