/**
 * Remove Class Filter Without Access to Class Object
 *
 * In order to use the core WordPress remove_filter() on a filter added with the callback
 * to a class, you either have to have access to that class object, or it has to be a call
 * to a static method.  This method allows you to remove filters with a callback to a class
 * you don't have access to.
 *
 * Works with WordPress 1.2+ (4.7+ support added 9-19-2016)
 * Updated 2-27-2017 to use internal WordPress removal for 4.7+ (to prevent PHP warnings output)
 *
 * @see https://gist.github.com/tripflex/c6518efc1753cf2392559866b4bd1a53
 *
 * @param string $tag         Filter to remove
 * @param string $class_name  Class name for the filter's callback
 * @param string $method_name Method name for the filter's callback
 * @param int    $priority    Priority of the filter (default 10)
 *
 * @return bool Whether the function is removed.
