Looking for bootstrap-modal.js and ember-data-localstorage.js

I started reading Ember.js in Action book.

In the very first app, author advises to download a number of js files.

There are 2 which I can't figure out where to download from:

1. bootstrap-modal.js
2. ember-data-localstorage.js

Googling didn't give any results.

Although, these scripts available in the book's source code, they're 2 years old. I wonder if those scripts are not used anymore or I will have to make them on my own...
