* 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.
