 * Iterates over own and inherited enumerable properties of an object,

 * and invoked with three arguments; (value, key, object). Callbacks may exit
 * iteration early by explicitly returning `false`.

 * @param {Object} object The object to iterate over.
 * @param {Function} [callback=identity] The function called per iteration.
 * @param {*} [thisArg] The `this` binding of `callback`.
 * @returns {Object} Returns `object`.
 * @example
 *
 * function Shape() {
