  3.  * Twenty Twelve functions and definitions
  4.  *
  5.  * Sets up the theme and provides some helper functions, which are used
  6.  * in the theme as custom template tags. Others are attached to action and
  7.  * filter hooks in WordPress to change core functionality.
  8.  *
  9.  * When using a child theme (see http://codex.wordpress.org/Theme_Development and
  10.  * http://codex.wordpress.org/Child_Themes), you can override certain functions
  11.  * (those wrapped in a function_exists() call) by defining them first in your child theme's
  12.  * functions.php file. The child theme's functions.php file is included before the parent
  13.  * theme's file, so the child theme functions would be used.
  14.  *
  15.  * Functions that are not pluggable (not wrapped in function_exists()) are instead attached
  16.  * to a filter or action hook.
  17.  *
