''' This class is identical to DatabaseObjects except that it implements the 
''' IEnumerable interface, therefore providing support for the "For Each" construct. 
''' If IEnumerable is not required then inherit from DatabaseObjects. Generally, 
''' inheriting from DatabaseObjectsEnumerable is preferable to DatabaseObjects as it 
''' generates simpler and more readable code.
