Duke project template

This is a greenfield Java project. It's named after the Java mascot Duke. Duke is a desktop app for managing tasks optimized for use via a Command Line Interface (CLI), while still having the benefits of a Graphical User Interface (GUI). Given below are instructions on how to use it.
