""" Defaults for images and headers

error_level is the problem level (see BatteryRunners) at which an error will be
raised, by the batteryrunners ``log_raise`` method.  Thus a level of 0 will
result in an error for any problem at all, and a level of 50 will mean no errors
will be raised (unless someone's put some strange problem_level > 50 code in).

``logger`` is the default logger (python log instance)

To set the log level (log message appears for problem of level >= log level),
use e.g. ``logger.level = 40``.

As for most loggers, if ``logger.level == 0`` then a default log level is used -
use ``logger.getEffectiveLevel()`` to see what that default is.

Use ``logger.level = 1`` to see all messages.
