Review the contents of Editor.java and TestEditor.java under Editor

directory to understand the requirements.

Use terminal to compile and run the program.

Manually Check to see if the files AntiHeros.txt and

AntiHerosViaUndo.txt are the same

Manually Check to see if the files Jokers.txt and JokersViaRedo.txt are

the same.
