* CONFIGURATION SECTION. 
* 
* 1) You must place your menu items here using the full path to each page. 
*			Example of full path> 'http://yoursite.com/somedirectory/page.html'
*
* 2a) Adding a new menu is easy. First give the menu an id.
*			Example of menu id>	 dn = 'dbas'; (<-- must use dn here as the variable)
*
* 2b) Then create the 'div' element to hold the id by passing the variable you defined (must be dn) and the 
* width of the menu to the 'startdiv' function: 
*			Example of menu div>	startdiv( dn, '150');
*
* 2c) Put it together like so>	  dn = 'dbas'; startdiv( dn, '150' );
*
* 3) Adding a menu item is also easy. Use this format for each menu item: 'url', dn, 'label' 
* Notice that dn has no quotes here in this example:
*			Example of menu item>	bi('http://yoursite.com/index.html', dn, 'Home Page');
*
* 4) Finish by ending the 'div' element:
*			Example of end div>	enddiv();
*
* 5) Don't forget to add any menu you create to the style sheet!
*
