Default class used by Sloop::Server to create objects representing accepted client connections. Conjoins the functionality of its parents, Sloop::Client and Sloop::Socket::Standard.
Invocation is the same as for the Sloop::Client superclass (although sloop client objects should not be created except by the server).
Sloop::Client::Regular sets the 'id' field inherited from Sloop::Base to 'fdN', where N is the file descriptor number.
The API is entirely inherited from Sloop::Client.
