- Properly marked sync command as not displaying IDs, therefore no GC.
- Implemented the high-level communications, still without TLS. - Includes temporary diagnostics, and unlocalized error messages. These will converge upon proper and useful error messages as the command matures.
- Added a ::send method to CmdSync to perform the transfer. Note that this does not yet include any TLS.
- Added the stub of the sync command.
