 * Extension class for custom enable/disable/purge actions
 *
 * NOTE TO EXTENSION DEVELOPERS:
 * Normally it is not necessary to define any functions inside the ext class below.
 * The ext class may contain special (un)installation commands in the methods
 * enable_step(), disable_step() and purge_step(). As it is, these methods are defined
 * in phpbb_extension_base, which this class extends, but you can overwrite them to
 * give special instructions for those cases. This extension must do this because it uses
 * the notifications system, which requires the methods enable_notifications(),
 * disable_notifications() and purge_notifications() be run to properly manage the
 * notifications created by it when enabling, disabling or deleting this extension.
