Description:


Useful for debugging - stream operations are logged in human readable form
on a separate logger stream, while stream operations are forwarded to the underlying
loggedStream.

Unfinished - may need more protocol to be intercepted.

sample use, logging operations on a socket stream:
    sock := ... Socket connectTo: ...
    s := LoggingStream new loggedStream: sock.
    ...
    use s instead of sock
    ...
