logPaths is an (optional) list of strings to use as paths to test for writing. If the file can be created/written to,

it will be used (assuming you have no higher-level loggers available).

See the documentation for GetLogger for details on other arguments.

Only the first logPaths entry that "works" will be used, later entries will be ignored.

Currently this will almost always return a WinLogger.
