Intended usage for `<test-group>`s names and descriptions, as additional to PAGS group names and descriptions?  I don't see this concept offhand in [PAGSGroupStoreConfig.xml](https://github.com/Jasig/uPortal/blob/74bb37d2354001d817e1cee247276c1f329f813e/uportal-war/src/main/resources/properties/groups/PAGSGroupStoreConfig.xml)?  YAGNI?  If we are gonna need it, examples of intended usage?
