 * @module modifiers/snapEdges
 *
 * @description
 * This modifier allows snapping of the edges of targets during resize
 * interactions.
 *
 * ```js
 * interact(target).resizable({
 *   snapEdges: {
 *     targets: [interact.snappers.grid({ x: 100, y: 50 })],
 *   },
 * })
 *
 * interact(target).resizable({
 *   snapEdges: {
 *     targets: [
 *       interact.snappers.grid({
 *        top: 50,
 *        left: 50,
 *        bottom: 100,
 *        right: 100,
 *       }),
