Split string by split character space(' ') and indent('\t') as default

        Examples:
            >>> StringClass.split_string('exec -ini test.ini', ' ')
            ['exec', '-ini', 'test.ini']

        Args:
            str_src: source string
            spliters: e.g. [' ', '\t'], [], ' ', None
            elim_empty: Eliminate empty (i.e., '') or not.

        Returns:
            split sub-strings as list
