* Rename variable 'traffic' to 'trafficPerSecondQueue' and 'trafficInfoQueue' * Remove class QueueLast<T> by using linq Queue.Last() * Slight changes, such as rename, move several variables from function domain to class domain to improve performance. Logic remains the same. * Update the logic of copying queue from Controller to View. * Move the TrafficInfo declaration into LogForm class Overwise, the VS UI designer does not work.
