Feature request enable access to logpath for meta modules

It would make most sense for meta modules to handle their own logging, but at the moment they don't have access to the output path. This could be a standard init argument.

Start by locating the meta module initialization entry points and the code that currently receives or writes the output path. Trace how modules are constructed and determine where a standard initialization argument would fit. Done means meta modules can access the output path for their own logging without breaking existing initialization.
