/* 
The navigation system.  There are 4 different navigation areas on a page:
primary, secondary, auxilary, and footer.  Each is defined in an array.

There are also two functions: one to display the page header with primary,
secondary, and aux navigation areas; and one to display the page footer with
its navigation area.

The reason for putting the navigation system into Javascript is so that the
menus can be maintained in one place.  In addition, the menu format, text, and 
links will be consistent on all pages throughout the site.
