  3.  * Twenty Eleven functions and definitions
  4.  *
  5.  * Sets up the theme and provides some helper functions. Some helper functions
  6.  * are used in the theme as custom template tags. Others are attached to action and
  7.  * filter hooks in WordPress to change core functionality.
  8.  *
  9.  * The first function, twentyeleven_setup(), sets up the theme by registering support
  10.  * for various features in WordPress, such as post thumbnails, navigation menus, and the like.
  11.  *
  12.  * When using a child theme (see http://codex.wordpress.org/Theme_Development and
  13.  * http://codex.wordpress.org/Child_Themes), you can override certain functions
  14.  * (those wrapped in a function_exists() call) by defining them first in your child theme's
  15.  * functions.php file. The child theme's functions.php file is included before the parent
  16.  * theme's file, so the child theme functions would be used.
  17.  *
  18.  * Functions that are not pluggable (not wrapped in function_exists()) are instead attached
  19.  * to a filter or action hook. The hook can be removed by using remove_action() or
  20.  * remove_filter() and you can attach your own function to the hook.
  21.  *
  22.  * We can remove the parent theme's hook only after it is attached, which means we need to
  23.  * wait until setting up the child theme:
  24.  *
  25.  * <code>
  26.  * add_action( 'after_setup_theme', 'my_child_theme_setup' );
  27.  * function my_child_theme_setup() {
  28.  *     // We are providing our own filter for excerpt_length (or using the unfiltered value)
  29.  *     remove_filter( 'excerpt_length', 'twentyeleven_excerpt_length' );
  30.  *     ...
  31.  * }
  32.  * </code>
  33.  *
  34.  * For more information on hooks, actions, and filters, see http://codex.wordpress.org/Plugin_API.
