/* NAVIGATION EXPLANATION

== LINKS ==
	Create classes that attached a specific 'change content' function


== INITIAL LOAD ==
	The PHP CONTENT SWITCH loads the default content
		switch ($_article) { default: '_home.php' }

	
== NO SCRIPT ==

	MAP FLAT URLs
		Configure .HTACCESS to map (internally) FLAT URLs to QUERY STRING URLs
			 /home/welcome --> /home/home.php?article=welcome 
		The URL doesn't change
		Place RULES at the bottom of the file (after the CHANGE CONTENT rules)
		
	EXPAND TRUNCATED NAMES
		If files or sub-directoris have truncated names from what you want to show in the URL, remap them here
			RewriteRule ^vintage$ vintage_pop [R,NC]
			RewriteRule ^swings$ a_world_that_swings [R,NC]
		The [R] flag rewrites the URL in the address bar.
		
	PHP CONTENT SWITCH
		Set a relative path for each article
		Prefix article content with an (_) to...
			- Distinguish it from the FLAT URLs
			- Allow the template AND the default content to have the same name 
				home.php | _home.php
			- Easily identify templates from articles
		Articles can be in the same directory or in a sub-directory
			welcome: '_welcome.php'
			hello: '_hello/_hello.php'
		The PHP CONTENT SWITCH will re-load FLAT URLs using the article in the Query String
		
	
== DYNAMIC: CHANGE CONTENT FUNCTION ==

	Initial Page Load as above.
	On click, The CHANGE CONTENT function determines the action.

	FIND 'THIS'
		THIS PAGE is set by finding the id of <body>
			<body id="home">
		THIS ARTICLE is set by finding the id of the article
			#article #default | #article #welcome
	
	SET THE DEFAULT TO DEFALUT (LOL)	
		If the function is passed with only one paramater, set ARTICLE REQUEST to 'default'
			change_content ('gallery')
			if (article_request == null) {article_request = 'default';} 
		
	== SAME PAGE, CHANGE ARTICLE ==
		Load the ARTICLE REQUEST using the built in JQUERY function
			$('#article').load('_' + article_request); 
		Append the (_) to the ARTICLE REQUEST (see FLAT URLs)
		
		HTACCESS	
			Configure .HTACCESS to map _article_request to the correct URL
				RewriteRule ^_default$ _home.php [NC,L]
			Not needed if the name is the same
				_welcome.php | _welcome/ (sub-directory. see next)
	
		HTACCESS FOR SUB DIRECTORIES
			Articles can be in the same directory or in sub-directory.
			When using a sub-directory, add a .HTACCESS file to it and configure it with the article to load
				_welcome/_welcome.php use: DirectoryIndex _welcome.php

	== NEW PAGE, DEFAULT ARTICLE ==
		This simply loads a new PAGE using an ABSOLUTE URL
		The default article is set by the PHP CONTENT SWITCH
			document.location.href = '/' + page_request + '/';
			
	== NEW PAGE, ARTICLE 
		Load the new PAGE and ARTICLE using a FLAT URL
			document.location.href = '/' + page_request + '/' + article_request;
		This has a drawl back in that the url will show the that url after changing content (see below)

		FUTURE PROJECT
			Load the new PAGE and ARTICLE using a QUERY STRING URL
				document.location.href = '/' + page_request + '/' + page_request + '.php?article=' + article_request;
			Configure .HTACCESS to remove the QUERY STRING URLs in the address bar
				- We want to drop the query altogether.
