Serializing

The following methods are used for serializing Config objects back into INI files:

- {@link oaj.config.Config}
  - {@link oaj.config.Config#writeTo(Writer) writeTo(Writer)}
  - {@link oaj.config.Config#toString() toString()}

Both methods are thread safe.

The Config class implements the {@link oaj.Writable} which means it can be returned as-is by REST methods to be serialized as INI text.
