////////////// Declare the app menus

We tell guibroker what our menus are. Before the user reaches us, guibroker

renders hello.html and populates the page with these menu options.

As the user clicks on a menu option, we receive the message (#msg) associated

with that menu option. When we receive that message, MAE calls the method we

are here associating with the menu. It's menu registration & callback.

Here's the menu option Display->From DB, which queries the DB to determine the user's name, then says hello
