readability refactoring of #filter_applies?

Created by: AlexKVal

Not sure about methods naming. If those 'metadata' params (like in: filter_applies?(key, value, metadata=self) or configure_for_example(description, user_metadata) and others) would be Metadata, then code would be like: metadata.filter_for_locations?(value) metadata[key].filter_applies?(k, v) user_metadata.configure_for_example(description) and so on. Much concise and OOP.

Question: It would be nice if filtering methods "any_apply? all_apply? filter_applies?" and private "relevant_line_numbers" and others move into dedicated module ? (MetadataFiltering may be) The Metadata class would be cleaner and the filtering logic would be isolated.

and: filter_applies? - it seems it has to be private, but it's not big deal :)
