Commands:

1. Add a new entry to table:
ADD <TableRow data, comma-delimited>

2. Update an existing entry in a table:
UPDATE <TableRow data, comma-delimited>

3. Delete the entry from a table:
DELETE <TableRow data, comma-delimited>

4. Send the whole table:
TABLE <Array of TableRow data, Newline-delimited and comma-delimited>

5. Pass a message (from a client, to a client/server):
MESSAGE <messageData>
