Allows JSON data to be persisted easily by user scripts
此脚本不应直接安装，它是一个供其他脚本使用的外部库。如果您需要使用该库，请在脚本元属性加入：// @require https://update.cn-greasyfork.org/scripts/10443/56962/DataCache%20-%20Simple%20storage%20wrapper.js
Automates storing data as a JSON object. Example:
var cache = new DataCache('linked-urls');
cache.setValue('moo', 'http://google.com');
var moo = cache.getValue('moo', 'DEFAULT');
// --------------------------------------------------------------------------
GM_registerMenuCommand('Edit cache', function() {
cache.edit();
}, 'p');
Requires both GM_getValue and GM_setValue permissions to be granted to any user script that requires it.
