Log Summarizer Rewrite

Rewrite your log summarizer programs based on the comments you received in the code reviews and from the grader for the course. A few things to think about:

• Make sure you parse the command line correctly, sending appropriate error messages and usage reminders to standard error (System.err or sys.stderr or cerr, depending on your programming language). In particular, if the user types the wrong number of arguments, your program should not crash.
• Adhere to the specification. This includes the command-line specification as well as the output format specification.
• Get the program to work right.
• Improve your naming, your code organization, your commenting strategy, etc., as recommended in your code review.
• Use your language's built-in tools where appropriate (e.g. Python dictionaries, Java HashMaps or TreeMaps, etc.) instead of re-inventing the wheel.
• Anything that bugged you about the original program? Fix it.

Have fun.
