app-nav is an enhanced menu system.  It allows each Keel app to 
contribute pieces of the menu.  It then takes the logged-in user's 
authorization levels into account to display only those items that are 
permitted for the user.  It knows nothing about the particular 
web-clients, it just hands a series of (menu level, menu title, URL)  
combinations to a Javascript menu-generator.

Keel's business objects (models) know nothing about the client 
framework.  Navigation between models are done using generic "Command" 
objects which contain the next model to navigate to, and the parameters 
to apply.  On the client side, based on the  UI framework, use 
techniques documented on the following pages:
