<Author>
   Programmed by Scott Baker.

<Purpose>
   Logging layer for ravenlib. Primarily used to insulate ravenlib from
   arizonareport, sending messages to the standard python error logger
   instead.

   Call enable_arizonareport() to make this module use arizonareport instead of
   python logging.
