/**
* 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
