+ * @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 Leafet'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.
