     6  * theme as custom template tags. Others are attached to action and filter
       
     7  * hooks in WordPress to change core functionality.
       
     8  *
       
     9  * When using a child theme you can override certain functions (those wrapped
       
    10  * in a function_exists() call) by defining them first in your child theme's
       
    11  * functions.php file. The child theme's functions.php file is included before
       
    12  * the parent theme's file, so the child theme functions would be used.
