| /** |
| * Creates a deep clone of `value`. If a callback is provided it will be |
| * executed to produce the cloned values. If the callback returns `undefined` |
| * cloning will be handled by the method instead. The callback is bound to |
| * `thisArg` and invoked with one argument; (value). |
| * |
| * Note: This method is loosely based on the structured clone algorithm. Functions |
| * and DOM nodes are **not** cloned. The enumerable properties of `arguments` objects and |
| * objects created by constructors other than `Object` are cloned to plain `Object` objects. |
| * See http://www.w3.org/TR/html5/infrastructure.html#internal-structured-cloning-algorithm. |

| * @param {*} value The value to deep clone. |
