Messages that document the simulation run can be stored in the
log file. The protocol contains file operations, definitions of values
set by clicking the 
button in the info panel, as well
as a teaching protocol (cycles, parameters, errors). In addition, the
user can output data about the network to the log file with the help
of the info panel. If no log file is loaded, output takes place only
on stdout. If no file name is specified when clicking 
, a possibly open log file is closed and further output is
restricted to stdout.
