 class DataSource(object):
   '''
   Defines an abstraction for all DataSources.
 
   DataSources must have two public methods, get and Refresh. A DataSource is
   initialized with a ServerInstance and a Request (defined in servlet.py).
   Anything in the ServerInstance can be used by the DataSource. Request is None
   when DataSources are created for Refresh.
 
   DataSources are used to provide templates with access to data. DataSources may
   not access other DataSources and any logic or data that is useful to other
   DataSources must be moved to a different class.
