 * This function is needed to determine the calling parent module.

 * @param {Boolean} cache Indicates whether the rewired module should be cached by node so subsequent calls of require() will return the rewired module. Subsequent calls of rewire() will always overwrite the cache.
 * @return {*} the rewired module
