Concurrency and locking for HTML5 localStorage.

bower install lockablestorage

LockableStorage.lock('key', function () {
    // exclusive access to localStorage['key']
});

This code was written by Benjamin Dumke-von der Ehe and described in this post: http://balpha.de/2012/03/javascript-concurrency-and-locking-the-html5-localstorage/.

All I did was wrap it in AMD stuff and make it available as a Bower package.
