Sharpened the distinction between (Sympa) lists and (Softwerkskammer) groups by renaming some functions.
Added tests for groupsAndMembers.
Renamed the internalAPI files of groups and groupsAndMembers to groupsAPI and groupsAndMembersAPI, respectively.
More clarifications of groups vs. lists.
Now the function is invoked on the correct module (remains of refactoring...)
