LineObject is used for line-buffered connections
(end in \r\n or just \n). To use, simply override
lineReceived: in a subclass of LineObject. By
default, LineObject does absolutely nothing with
lineReceived except throw the line away. Use
line object if you simply want line-buffered input. This
can be used on IRC, telnet, etc.
Warning the underscore at the start of the
name of this instance variable indicates that, even
though it is not technically private, it is
intended for internal use within the package, and
you should not use the variable in other code.
