	// Accessors

	// Mutators for taskList 
	void addTaskToList(Task &t);					// Creates a task object and adds it to taskList
	void deleteTaskFromList(Task &t);				// If this causes taskList.empty(), delete List

	std::vector<Task> viewTaskList();				// Returns a copy of taskList
	std::vector<Task> viewTaskListDateSort(bool asc);		// Returns list of tasks sorted by Date, ascending or descending
	std::vector<Task> viewTaskListByStatus(Status s);		// Returns list of tasks filtered by status
	std::vector<Task> viewTaskListByPriority(Priority p);		// Returns list of tasks filtered by priority
	std::vector<Task> viewTaskListByVisiblity(Visiblity v);		// Returns list of tasks filtered by visilbity
};

I created the User class, each of which has a list of friends.

I added a notion of visibility, where public means that a Task is visible when a User's friend views their List. To support this, I added a method to view tasks by visibility. When a User's friend views their List using viewFriendsListOfTasks, this will call viewTaskListByVisibility(public), so that the friend will only see Tasks set to Public.

This reuses the previous code because all we've done is add a Visibility property to Task and an accessor in List. Otherwise, the design is the same.
