create meeting and getDate tests added
allocating static int from within class removed, int allocation handled by seperate class now.  This is for better unit testing but have also foreseen problem with allocating id when data is reloaded.  Don't want to force id allocation from static field.
removed binary files
removed id allocation logic from class, placed in seperate MakeId class (see previous commit)
more meeting tests added and implentation for empty contact set
