/*	This file serves as the primary JS include file for the main set of pages, and serves to:


	1) Store the strings for the navmenu HTML, etc.  Now formatted nicely as well as functional, thanks to the magic of the 'with' statement. ^_^  Modified and implemented as a single function that makes use of the 'nesting' variable

	2) House the functions for the auto-creation of the link pages for icons

	3) House a function that generates a string of concatenated '../' strings.  Function accepts any integer value; is thus more flexible than if it used strictly the 'nesting' variable

	4) Hold any generalized functions for site-wide use

	5) Hold class definitions (Submenu so far) and such, cleaning up iconset.js
