        """
        Return the value from the args dictionary that may be specified with any of the
        argument names in the list of synonyms.

        The synonyms argument may be a Jython list of strings or it may be a string representation
        of a list of names with a comma or space separating each name.

        The args is a dictionary with the keyword value pairs that are the arguments
        that may have one of the names in the synonyms list.

        If the args dictionary does not include the option that may be named by any
        of the given synonyms then the given default value is returned.

        NOTE: This method has to be careful to make explicit checks for value being None
        rather than something that is just logically false.  If value gets assigned 0 from
        the get on the args (command line args) dictionary, that appears as false in a
        condition expression.  However 0 may be a legitimate value for an input parameter
        in the args dictionary.  We need to break out of the loop that is checking synonyms
        as well as avoid assigning the default value if 0 is the value provided in the
        args dictionary.
