The cualsead binary will be the server
it delegates soon in Cualsea::Server::Loop and which
will redirect requests to MessageController.
Forking is not implemented and will be probably out of the
project scope since this is a demo program.
The MessageManager is pretty much inpired in the way
sftp comunicates, but we soon stop sending raw binary
data when we have comunicated the packet size to delegate
in json which is more useful in Perl than handling
fake struct logic.
