Changed all the Arrays (aka _the one_ array) to be zero based instead of
1 based. It was quite the effort, our determination was put to the test.
We laughed, we cried, and in the end we proved victorious.
Encapsulated all the fields in the Job class!
Encapsulated all the fields in the Task class!
Encapsulated all the fields in the EventList class.
Encapsulated all fields in the Machine class.
Changed the changeState method in the Machine class so that it no longer
is passed an integer representing the machine. Now, all machines have an
id which represents their place in the array.
Changed a few names of fields for readability in several classes, and
encapsulated fields in the MachineShopSimulator class. We also extracted
"setFinishTime" method from Machine.
