Week 9 Challenge: Task Manager. Implemented basic implementations and GUI. Challenges are of increasing difficulty: Writing tasks to a file, reading tasks from a file, sorting and filtering, and lastly add, edit, and delete functionality. There is starter code available for all but the last challenge. Club members should work in groups.
