Useful base class for exceptions that have a single exception message argument. Among other things, this method provides a reasonable default __str__() method.

Usage:

from grizzled.exception import ExceptionWithMessage

class MyException(ExceptionWithMessage):
    def __init__(self, msg):
        ExceptionWithMessage.__init__(self, msg)
