Detailed Description

CommandParameters, derived from wxFileConfig, is essentially doing the same things as the SettingsVisitor classes. It does text <-> binary conversions of parameters. It does not seem to be using actual file read/writing.

Should it be converted to using SettingsVisitor? Probably yes. SettingsVisitor leads to shorter code. And SettingsVisitor is more multi-functional since SettingsVisitor can report on signature, do the work of wxWidget validators, and can create default dialogs. However until that conversion is done, we need this class, and we use a pointer to one from within a SettingsVisitor when interfacing with the code that still uses it.
