   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.
