It's a good thing I make so many mistakes, so I can write checks to detect them.

Ready for merge.

Please update changeLog.md with new name. Please code indicators (back ticks) in the change log so the line would be:

Three new initialization options: simulatorFragmentation , simulatorBufferSize, and simulatorLatencyTimer. Together, these new options enable a more realistic simulator, mimicking different potential user computer systems.

something like that please, so people can read the change log and know where to look. Thanks! Once again love the new features flowing in!
