Error handling classes and functions.
This module exports a single function:
formatErrorMsg - Properly formats an error message.
It also exports several exception classes:
KickstartError - A generic exception class.
KickstartParseError - An exception for errors relating to parsing.
KickstartValueError - An exception for errors relating to option
processing.
KickstartVersionError - An exception for errors relating to unsupported
syntax versions.
