/**
* Omphaloskepsis functions and definitions

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

* @link https://codex.wordpress.org/Child_Themes
*
* Functions that are not pluggable (not wrapped in function_exists()) are
* instead attached to a filter or action hook.
