 * A "match" is a data structure which acts like a mask or expression to match
 * certain windows or not. For example, when using commands, you can specify a
 * command like this: [title="*Firefox*"] kill. The title member of the match
 * data structure will then be filled and i3 will check each window using
 * match_matches_window() to find the windows affected by this command.
