[cs615asa] [project] Initial commit for argument parsing

[Charles Magyar IV]

Professor - We've created a code_review subchannel in the slack.

Would it be acceptable to move these reviews to the slack where the class can then vote on these pull requests?

Also, we may want to have another entity handling pull-requests.
