Version 0.2
Made the following changes:

• Implemented task addition, deletion, and reordering.
• Fixed a bug in assignment list tooltips that caused some characters to be omitted.
• Enabled the ability to add assignments in the class / subject view.
• Now keeping the list of subjects sorted.
• Added some "Not yet implemented" dialogs for those bits that aren't quite all there.

Version 0.1
The first instance of The Round Tuit is most of the way there. It's still missing the ability to create tasks for individual assignments. But apart from that it's functional enough for daily use.
