ILogLineColumnizerCallback
This is for some really special cases in where you need additional infos about the LogFile or get specific lines. Most of the time you can ignore this parameter.
Implement the IColumnizerConfigurator Interface in your columnizer.
Configure This is called when the user clicks on the "Config" button. There you can show a Dialog. You have to implement the whole logic of handling Save/Cancel/store of settings by yourself.
Load Called after the columnizer is loaded from LogExpert. Load there your saved configuration and maybe if there is no config some defaults.
