+/**
+ * Creates a deep clone of `value`. If `customizer` is provided it's invoked
+ * to produce the cloned values. If `customizer` returns `undefined` cloning
+ * is handled by the method instead. The `customizer` is bound to `thisArg`
+ * and invoked with up to three argument; (value [, index|key, object]).
+ *
+ * **Note:** This method is loosely based on the
+ * [structured clone algorithm](http://www.w3.org/TR/html5/infrastructure.html#internal-structured-cloning-algorithm).
+ * The enumerable properties of `arguments` objects and objects created by
+ * constructors other than `Object` are cloned to plain `Object` objects. An
+ * empty object is returned for uncloneable values such as functions, DOM nodes,
+ * Maps, Sets, and WeakMaps.

+ * @param {*} value The value to deep clone.
+ * @param {Function} [customizer] The function to customize cloning values.
+ * @param {*} [thisArg] The `this` binding of `customizer`.
+ * @returns {*} Returns the deep cloned value.
+ * @example
+ *
+ * var users = [
+ *   { 'user': 'barney' },
+ *   { 'user': 'fred' }
+ * ];
+ *
+ * var deep = _.cloneDeep(users);
+ * deep[0] === users[0];
+ * // => false
+ *
+ * // using a customizer callback
+ * var el = _.cloneDeep(document.body, function(value) {
+ *   if (_.isElement(value)) {
+ *     return value.cloneNode(true);
+ *   }
+ * });
+ *
+ * el === document.body
+ * // => false
+ * el.nodeName
+ * // => BODY
+ * el.childNodes.length;
+ * // => 20
