+ * Displays an animated hourglass icon. Suppresses all `navigation` events,
+ * making it impossible for the user to exit the view by pressing the back key.
+ * 
+ * <img src="../images/loading.png" width="200" alt="Sample screenshot of the view" />
+ * 
+ * ```js
+ * let eventLoop = require("event_loop");
+ * let gui = require("gui");
+ * let loadingView = require("gui/loading");
+ * ```
+ * 
+ * This module depends on the `gui` module, which in turn depends on the
+ * `event_loop` module, so they _must_ be imported in this order. It is also
+ * recommended to conceptualize these modules first before using this one.
+ * 
+ * # Example
+ * For an example refer to the GUI example.
+ * 
+ * # View props
+ * This view does not have any props.
+ * 
+ * @version Added in JS SDK 0.1
