CHANGES: Symbol library file format has been converted to s-expressions. Add support code for picking apart symbols at some future junction that will allow full inheritance conversion of existing symbol libraries. For now, symbols arranged by unit and body style numbers are nested for round robin testing of symbol libraries once the parser is complete.
