/**
* Twenty Twelve functions and definitions
*
* Sets up the theme and provides some helper functions. Some helper functions
* are used in the theme as custom template tags. Others are attached to action and
* filter hooks in WordPress to change core functionality.
*
* The first function, twentytwelve_setup(), sets up the theme by registering support
* for various features in WordPress, such as a custom background and a navigation menu.
*
* When using a child theme (see http://codex.wordpress.org/Theme_Development and
* http://codex.wordpress.org/Child_Themes), you can override certain functions
* (those wrapped in a function_exists() call) by defining them first in your child theme's
* functions.php file. The child theme's functions.php file is included before the parent
* theme's file, so the child theme functions would be used.
*
* Functions that are not pluggable (not wrapped in function_exists()) are instead attached
* to a filter or action hook.
*
* For more information on hooks, actions, and filters, see http://codex.wordpress.org/Plugin_API.
*
* @package WordPress
* @subpackage Twenty_Twelve
