	/**
	 * Redux Framework shortcode extension class. Takes the common WordPress functions `wp_get_theme()` and `bloginfo()` and a few other functions and makes them accessible via shortcodes. Below you will find a table for the possible shortcodes and their values.
	 * | shortcode | Function | Description |
	 * |-----------|----------|-------------|
	 * | blog-name | bloginfo("name") | Displays the "Site Title" set in Settings > General. This data is retrieved from the "blogname" record in the wp_options table. |
	 * | blog-description | bloginfo("description") |  Displays the "Tagline" set in Settings > General. This data is retrieved from the "blogdescription" record in the wp_options table.|
	 * | blog-wpurl | bloginfo("wpurl") |  Displays the "WordPress address (URL)" set in Settings > General. This data is retrieved from the "siteurl" record in the wp_options table. Consider using **blog-root_url** instead, especially for multi-site configurations using paths instead of subdomains (it will return the root site not the current sub-site). |
	 * | blog-root_url | site_url() |  Return the root site, not the current sub-site. |
	 * | blog-url | home_url() |  Displays the "Site address (URL)" set in Settings > General. This data is retrieved from the "home" record in the wp_options table. |
	 * | blog-admin_email | bloginfo("admin_email") |  Displays the "E-mail address" set in Settings > General. This data is retrieved from the "admin_email" record in the wp_options table.|
	 * | blog-charset | bloginfo("charset") |  Displays the "Encoding for pages and feeds" set in Settings > Reading. This data is retrieved from the "blog_charset" record in the wp_options table. Note: In Version 3.5.0 and later, character encoding is no longer configurable from the Administration Panel. Therefore, this parameter always echoes "UTF-8", which is the default encoding of WordPress.|
	 * | blog-version | bloginfo("version") |  Displays the WordPress Version you use. This data is retrieved from the $wp_version variable set in wp-includes/version.php.|
	 * | blog-html_type | bloginfo("html_type") |  Displays the Content-Type of WordPress HTML pages (default: "text/html"). This data is retrieved from the "html_type" record in the wp_options table. Themes and plugins can override the default value using the pre_option_html_type filter.|
	 * | blog-text_direction | bloginfo("text_direction") |  Displays the Text Direction of WordPress HTML pages. Consider using **blog-text_direction_boolean** instead if you want a true/false response. |
	 * | blog-text_direction_boolean | is_rtl() |  Displays true/false check if the Text Direction of WordPress HTML pages is left instead of right |
	 * | blog-language | bloginfo("language") |  Displays the language of WordPress.|
	 * | blog-stylesheet_url | get_stylesheet_uri() |  Displays the primary CSS (usually style.css) file URL of the active theme. |
	 * | blog-stylesheet_directory | bloginfo("stylesheet_directory") |  Displays the stylesheet directory URL of the active theme. (Was a local path in earlier WordPress versions.) Consider echoing get_stylesheet_directory_uri() instead.|
	 * | blog-template_url | get_template_directory_uri() |  Parent template uri. Consider using **blog-child_template_url** for the child template URI. |
	 * | blog-child_template_url | get_stylesheet_directory_uri() | Child template URI. |
	 * | blog-pingback_url | bloginfo("pingback_url") |  Displays the Pingback XML-RPC file URL (xmlrpc.php).|
	 * | blog-atom_url | bloginfo("atom_url") |  Displays the Atom feed URL (/feed/atom).|
	 * | blog-rdf_url | bloginfo("rdf_url") |  Displays the RDF/RSS 1.0 feed URL (/feed/rfd).|
	 * | blog-rss_url | bloginfo("rss_url") |  Displays the RSS 0.92 feed URL (/feed/rss).|
	 * | blog-rss2_url | bloginfo("rss2_url") |  Displays the RSS 2.0 feed URL (/feed).|
	 * | blog-comments_atom_url | bloginfo("comments_atom_url") |  Displays the comments Atom feed URL (/comments/feed).|
	 * | blog-comments_rss2_url | bloginfo("comments_rss2_url") |  Displays the comments RSS 2.0 feed URL (/comments/feed).|
	 * | login-url | wp_login_url() | Returns the WordPress login URL. |
	 * | login-url | wp_logout_url() | Returns the WordPress logout URL. |
	 * | current_year | date("Y") | Returns the current year. |
	 * | theme-name | $theme_info->get("Name") | Theme name as given in theme's style.css |
	 * | theme-uri | $theme_info->get("ThemeURI") | The path to the theme's directory |
	 * | theme-description | $theme_info->get("Description") | The description of the theme |
	 * | theme-author | $theme_info->get("Author") | The theme's author |
	 * | theme-author_uri | $theme_info->get("AuthorURI") | The website of the theme author |
	 * | theme-version | $theme_info->get("Version") | The version of the theme |
	 * | theme-template | $theme_info->get("Template") | The folder name of the current theme |
	 * | theme-status | $theme_info->get("Status") | If the theme is published |
	 * | theme-tags | $theme_info->get("Tags") | Tags used to describe the theme |
	 * | theme-text_domain | $theme_info->get("TextDomain") | The text domain used in the theme for translation purposes |
	 * | theme-domain_path | $theme_info->get("DomainPath") | Path to the theme translation files |
