In the fourth storyboard, the Add, Delete, Update, Group, and Refresh buttons were grouped
together on the right-hand side of the "page". The Start and Due date fields, still
separated into the day-month-year, now have "/" (slashes) in between the fields to make
the interface clearer for the user. A save button was added to the bottom of the screen
so that the user can save the changes he/she made to the to-do list. This should be our
final version.
