/*
This module provides easy access to the CSRF token and caches
it for re-use. It also exposes some values commonly used in relation
to the CSRF token (header key and headers object).
If you need to refresh the csrfToken for some reason, just call `init` and
then use the accessors as you would normally.
If you need to compose a headers object, use the spread operator:
```
headers: {
...csrf.headers,
someOtherHeader: '12345',
}
```
see also http://guides.rubyonrails.org/security.html#cross-site-request-forgery-csrf
and https://github.com/rails/jquery-rails/blob/v4.3.1/vendor/assets/javascripts/jquery_ujs.js#L59-L62
