/**
 * This file defines all the functions of the theme. This includes theme features, 
 * sidebars, menus, options, etc.
 * 
 * The first function, bloggito_theme_setup(), sets up the theme by registering support
 * for WordPress and Hybrid Core features, such as theme layouts, post formats, etc.
 * 
 * You can override these features and functions in your child theme by defining them in your
 * child theme's functions.php file. Please use the 'after_setup_theme' hook to override the
 * parent theme features. Using a priority of 11 will make sure changes run after the parent
 * theme's functions are loaded. Using a priority of 9 will make your changes load first.
