/**
 * Custom ModelLoader using Volley with basic authentication
 *
 * This is basically a copy of VolleyUrlLoader present in the Glide library, which couldn't be
 * extended because it has the requestQueue as a private member, and we'll need access to it to
 * pass it to the StreamLoader.
 *
 * This just serves to create the VolleyBasicAuthStreamLoader where the basic authentication
 * is implemented.
