/**
 * Bulk edit all downloads with variable price options
 *
 * This code should only be executed when needed. The purpose is to find
 * all downloads with variable pricing, and update their respective variable
 * pricing labels (Option Name) based strings given in the custom function.
 *
 * The easiest way to use the function is with the following WordPress plugins:
 *
 * Debug Bar: https://wordpress.org/plugins/debug-bar/
 * Debug Bar Console: https://wordpress.org/plugins/debug-bar-console/
 *
 * Once installed and activated, enter the following code into the PHP section
 * of the Debug Bar - Console interface (be sure not to delete the opening PHP tag).
 * Click "Run" to execute the code. That will immediately modify the data, though
 * there's no visual indication. Now in a separate tab, visit one of your downloads
 * with variable pricing and it should be updated to reflect the new labels.
 *
 * ALWAYS test on your staging/dev site first and back-up your data before using.
