Configuration file with list of ignored files

It would be nice not to see files from e.g. `db/migrate/` inside my Skunk summary output. These files need to exist in a codebase but do not carry any meaningful weight when it comes to that codebase's maintainability. Do you think it could be useful to add a configuration file where file globs could be provided for files to ignore? Rubocop etc. definitely provide some prior art that could be copied here.
