set_logger(logger)
Sets a logger object for exceptions and error information
Parameters
logger : object
A logger object, generally from the standard logger package.Comments
Once a logger has been set for the module, unhandled exceptions, such as 
from a window's WNDPROC, will be written (via logger.exception()) to the log 
instead of to stderr. 
Note that using this with the Python 2.3 logging package will prevent the 
traceback from being written to the log.  However, it is possible to use 
the Python 2.4 logging package directly with Python 2.3
