-/**
- * A client-side key-value store with support for indexes.
- *
- * Many browsers support IndexedDB—a web standard for
- * an indexed database.
- * By storing data on the client in an IndexedDB,
- * a web app gets some advantages, such as faster performance and persistence.
- * To find out which browsers support IndexedDB,
- * refer to [Can I Use?](http://caniuse.com/#feat=indexeddb)
- *
- * In IndexedDB, each record is identified by a unique index or key,
- * making data retrieval speedy.
- * You can store structured data,
- * such as images, arrays, and maps using IndexedDB.
- * The standard does not specify size limits for individual data items
- * or for the database itself, but browsers may impose storage limits.
- *
- * ## Using indexed_db
- *
- * The classes in this library provide an interface
- * to the browser's IndexedDB, if it has one.
- * To use this library in your code:
- *
- *     import 'dart:indexed_db';
- *
- * A web app can determine if the browser supports
- * IndexedDB with [IdbFactory.supported]:
- *
- *     if (IdbFactory.supported)
- *       // Use indexeddb.
- *     else
- *       // Find an alternative.
- *
- * Access to the browser's IndexedDB is provided by the app's top-level
- * [Window] object, which your code can refer to with `window.indexedDB`.
- * So, for example,
- * here's how to use window.indexedDB to open a database:
- *
- *     Future open() {
- *       return window.indexedDB.open('myIndexedDB',
- *           version: 1,
- *           onUpgradeNeeded: _initializeDatabase)
- *         .then(_loadFromDB);
- *     }
- *     void _initializeDatabase(VersionChangeEvent e) {
- *       ...
- *     }
- *     Future _loadFromDB(Database db) {
- *       ...
- *     }
- *
- *
- * All data in an IndexedDB is stored within an [ObjectStore].
- * To manipulate the database use [Transaction]s.
- *
- * ## Other resources
- *
- * Other options for client-side data storage include:
- *
- * * [Window.localStorage]—a
- * basic mechanism that stores data as a [Map],
- * and where both the keys and the values are strings.
- *
- * * [dart:web_sql]—a database that can be queried with SQL.
- *
- * For a tutorial about using the indexed_db library with Dart,
- * check out
- * [Use IndexedDB](http://www.dartlang.org/docs/tutorials/indexeddb/).
- *
- * [IndexedDB reference](http://docs.webplatform.org/wiki/apis/indexeddb)
- * provides wiki-style docs about indexedDB
