/**
 * This class allows you to use native APIs to take photos using the device camera.
 *
 * When this singleton is instantiated, it will automatically select the correct implementation depending on the
 * current device:
 *
 * - Sencha Packager
 * - Cordova
 * - Simulator
 *
 * Both the Sencha Packager and Cordova implementations will use the native camera functionality to take or select
 * a photo. The Simulator implementation will simply return fake images.
 *
 * ## Example
 *
 * You can use the {@link Ext.device.Camera#capture} function to take a photo:
 *
 *     Ext.device.Camera.capture({
 *         success: function(image) {
 *             imageView.setSrc(image);
 *         },
 *         quality: 75,
 *         width: 200,
 *         height: 200,
 *         destination: 'data'
 *     });
 *
 * See the documentation for {@link Ext.device.Camera#capture} all available configurations.
 *
