    [2541] Documentation and cleanup
    
    don't duplicate the duplicate zone check in sqlite3 accessor's addZone()
    added documentation

    [2541] add createZone() to DataSourceClient interface
    
    Note: currently called createZone so as not to interfere with an existing addZone() call in MemoryClient.
    Instead of pure virtual I made it have a default 'NotImplemented' method.
    Also, the DatabaseClient holds the transaction (not the SQLite3Accessor); we could do it on that level but we already have a transaction API on a higher level and it makes a little bit more sense to me to do it there
