+/** rft/ui/content - Load page content
+ *
+ * The rft/ui/content module is responsible for loading content in the app.
+ * Content is loaded by calling:
+ *    content.goTo('pageId');
+ * The page is then loaded from pages/pageId.html. This should contain one top node.
+ * This top node gets a _Page widget instantiated on it. The template should not
+ * specify another widget on the topnode. A page controller can be specified by
+ * the data-rft-mixin attribute to a class inherited from _PageController.
+ * You can also specify methods in the template in script tags as:
+ *     <script type="rft/method" data-rft-method-name="onVisit|onLeave">
+ *        // code
+ *     </script>
+ * The two relevant events are onVisit and onLeave. After loading and starting
+ * the complete page onVisit is called. Use this to link widgets together and
+ * load any dynamic content not handled by widget logic already.
+ * The event onLeave is called before navigating to another page. If false is 
+ * returned from this function, the navigation will be cancelled. You can use 
+ * this e.g. to ask confirmation of changed values are not saved.
