*
* 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

* theme's file, so the child theme functions would be used.
*
* Functions that are not pluggable (not wrapped in function_exists()) are instead attached
