Initial working commit
Renamed CDEMessage to CDEMessages due to a conflict in Java compilation
Fixed some minor, mainly python-related, errors
- Needed to specify that we want the first tuple returned from struct.unpack
- Message component is node_dcid, not dcid
- Needed a str() call on the error_code
- Made it clearer that the function succeeds!
