KTLog writes the log information to ~/Library/Logs/processName.ktlog
It provides automatic log rolling once the filesize is over a threshold. The default file size is 5MB
KTLogWarn is the default level. Lower values are less chatty (fatal being rare), higher values are more chatty,
with debug being the chattiest.
By default KTLog will also log messages to the console (stderr)
