simulation: add simulation with scheduler (#71)

- Add new field in test.Event: HistoryIndex
   HistoryIndex allow us to access them by their position in event history.
- Record local time in test.App when receiving events.
- Add statisitics module for slices of test.Event.
- add new command line utility *dexcon-simulation-with-scheduler
   to verify the execution time of core.Consensus.
