*
* Provides a common navigation bar to a set of pages, dynamically
* making sure that the link to the current page isn't hyperlinked.
*
* Usage:
* In each file which will display the navigation bar:
* <?php include "navbar.php3"; ?>
*
* Edit $links_arr to contain the name of the link and the
* URL for link (can be relative or absolute URL).
*
* TODO:
* o Read array from a flat text file
* o Read array from database
* o Support for graphical buttons instead of just text
* o Support for frame targets
*
