 * @file
 * File picker and finder for device storages on Firefox OS devices
 *
 * This library provides an easy-to-use asynchronous interface for other Firefox OS apps to search for files
 * on Firefox OS devices. The library is based on an event-based architecture, letting developers build
 * beautiful asynchronous API for their apps.
 *
 * The `Finder` library is best used by developers looking to pick a file from the `sdcard` for their apps.
 *
 * This library depends on [EventEmitter](https://github.com/Wolfy87/EventEmitter) by Wolfy87, included with the
 * package.
