Help getting a list of usergroups from ACP

[Steve F]

I'm trying to make a add-on right now that will list publicly the usergroups from within the ACP, but I also need to be able to exclude certain groups if so desired.

I was told to use 1 of the following but I can't seem to find a good example anywhere on how I can pull the needed info and use it in my template.

XenForo_Model::create('XenForo_Model_UserGroup')->getAllUserGroupTitles();

or

$this->getModelFromCache('ModelName');

Currently all I have is a Listener.php. Where and how can I use one of the above so I can display the usergroups?

Thanks

I was able to figure this out After checking out some other add-ons and XenForo's Model UserGroup.
