        main_frame: bool,
        url: String,

    Console {
        level: String,

    },
}

Something the browser did that a trace records (issue #108).

Engines that can report page activity hand these to a recorder through EngineAdapter::trace_events; each maps to one js/src/traces/observers.js record.
