Renamed geteList into getEventList (it made more sense with camel case).
Also created a new method inside MachineShopSimuator (MSS) that calls
eList.setFinishTime. Previously the Machine class would call
setFinishTime through MSS which was long and ugly. Now all Machine has
to do is call the method from MSS and MSS will do it!
Cleaned up some more code for method setFinishTime() by directly getting
the timeNow field. Also noticed that a different time of setFinishTime()
was being called in the Machine class thus we created another method
call noMoreJob that sets the finish time to largeTime. Machine class
looks cleaner. Seems like Machine class looks good for now.....taking a
look at the Job class, we created a method call jobDone that tells MSS
that a job with ID is done. This shortens the code in the Job class and
allows MSS to call timeNow (Eventually we can get rid of the getters!).
