+Creates a modal dialog to give a waiting feedback to users
+You can only show and dismiss the dialog, it will block user interactions. You can set the text appearing in the dialog
+NOTE: this is not a progress dialog, you can not show progress
+
+    // To SHOW a modal waiting dialog
+    window.plugins.waitingDialog.show("Your dialog text");
+
+    // To HIDE the dialog
+    window.plugins.waitingDialog.hide();
+    
+If you want to show a waiting dialog for a certain amount of time, you can use javascript setTimeout
+
+	// show dialog
+	window.plugins.waitingDialog.show("Your dialog text");
+	// automatically hide dialog after 5 seconds
+	setTimeout(function() {window.plugins.waitingDialog.hide();}, 5000);
