/**
 * This code snippet is an example of how to implemnt a callback for the
 * conversion of custom products of type "booking". Please note that this is just
 * a skeleton, and no conversion is actually performed. The purpose of this code
 * is to illustrate how to interact with the Currency Switcher to add custom
 * conversion logic for custom product types.
 *
 * HOW TO USE THIS CODE
 * Simply add the code to the bottom of your theme's functions.php file, and it
 * will run automatically. For more information: https://www.skyverge.com/blog/add-custom-code-to-wordpress/
