* Hitachi GST Internet Navigation Script
* 
* author: Ryan Huff, IBM Global Services, rlhuff@us.ibm.com
* 
* The purpose of this script is to make an easily maintainable
* navigation structure.
* 
* Tier 2 (Products, About) may not be *created* here
* 
* To add a new Tier 3 link (e.g. Products/Awards, etc) create a new Tier 3 Node
* within the appropriate Tier 2.
*   - The Tier 3 Node consists of the node name (e.g. Benefits, etc), and the 
*		Tier 3 Node URL.
*
* In the "parent" HTML file, two parameters should be defined: nav2 and nav3.
*   - nav2 is the Tier 2 Node name of the currently selected Tier 2 site.
*   - nav3 is the Tier 3 Node name of the currently selected Tier 3 within the 
*		Tier 2.
* 
* The "renderNavigation()" function should be called from the parent HTML file
* in the place where the navigation menu should be displayed.
