an instance of an class iterator for Config
an instance of the MetaConfig class
delegate which returns appender instances to write to a file
A delegate that returns a Layout instance from a name, or throws on error. By default, wraps ocean.util.log.Config.newLayout
true if the InsertConsole appender should be used (needed when using the AppStatus module)
Sets up logging configuration for ocean.util.log.Logger
Calls the provided file_appender delegate once per log being configured and passes the returned Appender to the Logger.add method.
This is an extra overload because using a delegate literal as a parameter's default argument causes linker error in D1.
