started added filter classes. Will come back to this
Added basic sorting functionality: if you click on a header in reqlist, it will sort in ascending order if the elements in the column implement Comparable
added filter functionality. No gui yet though.
Headers titles now change to reflect how it was sorted, and it flip flops between sorting ascending and descending.  -Michael Perrone

Made the grayed out sub division dropdown set back to None when switching to pie.
Actually implemented the shell of tests I had previously. -Michael Perrone
Added to AcceptanceTestView the ability to grey out the edit button or add button
