Groups2009 code:
Group._load_group() returns members and member_groups. Minor code refinements. http://hg.moinmo.in/moin/1.9-groups-dmilajevs/rev/415338464695
BaseBackend.groups_with_member() method was added. Test.GroupManager.test_membergroups() removed. http://hg.moinmo.in/moin/1.9-groups-dmilajevs/rev/3c0ce322472a
GroupManager became compose backend and was moved to backends directory. Unnecessary tests were removed. http://hg.moinmo.in/moin/1.9-groups-dmilajevs/rev/89497de6165d
It is possible to import backends as 'from Moin.groups import WikiGroups, ConfigGroups, CompositeGroups'. Compose backend was renamed to Composite. http://hg.moinmo.in/moin/1.9-groups-dmilajevs/rev/a1018d829c3e
