/*	This template is, perhaps, the most important template in the theme. It
	contains the main template layer that displays the header and footer of
	the forum, namely with main_above and main_below. It also contains the
	menu sub template, which appropriately displays the menu; the init sub
	template, which is there to set the theme up; (init can be missing.) and
	the linktree sub template, which sorts out the link tree.

	The init sub template should load any data and set any hardcoded options.

	The main_above sub template is what is shown above the main content, and
	should contain anything that should be shown up there.

	The main_below sub template, conversely, is shown after the main content.
	It should probably contain the copyright statement and some other things.

	The linktree sub template should display the link tree, using the data
	in the $context['linktree'] variable.

	The menu sub template should display all the relevant buttons the user
	wants and or needs.

	For more information on the templating system, please see the site at:
	https://www.simplemachines.org/

		You don't need to manually load index.css, this will be set up for you.
		Note that RTL will also be loaded for you.
		To load other CSS and JS files you should use the functions
		loadCSSFile() and loadJavaScriptFile() respectively.
		This approach will let you take advantage of SMF's automatic CSS
		minimization and other benefits. You can, of course, manually add any
		other files you want after template_css() has been run.

	*	Short example:
			- CSS: loadCSSFile('filename.css', array('minimize' => true));
			- JS:  loadJavaScriptFile('filename.js', array('minimize' => true));
			You can also read more detailed usages of the parameters for these
			functions on the SMF wiki.

	*	Themes:
			The most efficient way of writing multi themes is to use a master
			index.css plus variant.css files. If you've set them up properly
			(through $settings['theme_variants']), the variant files will be loaded
			for you automatically.
			Additionally, tweaking the CSS for the editor requires you to include
			a custom 'jquery.sceditor.theme.css' file in the css folder if you need it.

	*	MODs:
			If you want to load CSS or JS files in here, the best way is to use the
			'integrate_load_theme' hook for adding multiple files, or using
			'integrate_pre_css_output', 'integrate_pre_javascript_output' for a single file.
