 * removeDefaultOwnerPermissions.groovy
 *
 * In Grouper 2.4.0, when new groups and stems are created, the creator is no longer added as an admin
 * if they are in the wheel group. The explicit access is unnecessary since users in the wheel group automatically
 * have admin access even without the permission. This script performs a cleanup of these permissions, looping through
 * a defined list of subjects (mixed ids/identifiers), and removing the admin access from the groups and stems.
 * This cleanup could remove many thousands of excess memberships from the database, possibly improving performance.
