A polyfill to enable IndexedDB using WebSql.
IndexedDB is not supported on all browsers. This IndexedDB polyfill exposes the IndexedDB API in unsupported browsers using WebSQL. This shim is basically an IndexedDB-WebSql adapter.
Using this polyfill, you can use a single offline storage API across browsers (Opera, Safari, Firefox, Chrome and IE10) and even mobile devices (Phonegap on iOS and Android).
To use the polyfill, simply download the concatenated, minified product from the
dist directory and include it in your HTML document.

window.IndexedDB object available for you to use.
If you want to force the use of this polyfill (on Chrome where both IndexedDB and WebSql are supported), simply use
